[00:00:30] Hello and welcome to a short news segment from BBC Persian TV.
[00:00:34] The Speaker of the Iranian Parliament has criticized factions that, according to him, are leading the country
[00:00:38] towards an endless war. Mohammad Bagher
[00:00:42] Qalib also confirmed that Iran has sent messages and conditions
[00:00:45] to the United States through mediators. Mr. Qalib
[00:00:49] said Iran should both fight and negotiate.
[00:00:52] Earlier, Mohsen Rezaee, Secretary of Iran's Supreme National Security Council,
[00:00:56] said that Iran is awaiting America's response. The end
[00:01:00] of conflict on all fronts, the release of frozen Iranian assets,
[00:01:04] and the lifting of the naval blockade are among the demands
[00:01:07] set by Tehran.
[00:01:08] Turkey
[00:01:11] has announced its joint effort with several other
[00:01:14] countries to present a new proposal aimed at bringing
[00:01:18] Iran and the United States closer to an agreement.
[00:01:22] Hakan Fidan, the Turkish Foreign Minister, without elaborating
[00:01:25] on the details of the plan, said there is deep distrust between
[00:01:29] Tehran and Washington in these negotiations
[00:01:38] to pursue their interests. At the same time, the Pakistani Interior Minister is scheduled to visit Tehran today. Pakistan has been a mediator between Iran
[00:01:42] and the US in recent months.
[00:01:44] The US President has
[00:01:47] cut short his weekend holiday at Camp David
[00:01:51] and returned to the White House earlier than scheduled.
[00:01:54] According to Axios, Donald Trump was supposed to return
[00:01:58] from Camp David to Washington today. The White House
[00:02:02] has not yet announced the reason for this decision.
[00:02:05] Meanwhile, US embassies in West Asian countries
[00:02:09] have issued urgent security warnings for American citizens
[00:02:13] in the region. Saudi Arabia
[00:02:16] has confirmed that Houthi
[00:02:19] rebels in Yemen attempted yesterday to target
[00:02:23] the capital with a ballistic missile.
[00:02:27] Riyadh says it intercepted and destroyed the missile.
[00:02:31] Earlier, media reported hearing several explosions
[00:02:34] in Riyadh, and there were also reports of a smoke plume near
[00:02:38] the city's airport. According to these reports,
[00:02:42] a fuel tank belonging to the Aramco oil company
[00:02:46] near the airport caught fire.
[00:02:49] Meanwhile, the United States has warned that the conflict between Saudi Arabia
[00:02:53] and the Houthis, who are supported by Iran, could rapidly
[00:02:56] escalate. Ukraine
[00:03:03] has carried out widespread drone attacks on Moscow
[00:03:07] and its surrounding areas. The mayor of Moscow described
[00:03:10] the attack as unprecedented in scale, saying it involved
[00:03:14] 450 drones. In these attacks, two
[00:03:18] people were killed, and an oil refinery was targeted.
[00:03:21] More than 30 flights were also canceled
[00:03:24] or delayed. These attacks coincided with the third
[00:03:27] and final day of voting in Russia's parliamentary elections.
[00:03:31] Only parties close to the Kremlin
[00:03:35] participated in these elections.
[00:03:36] Thank you for joining
[00:03:40] us for this news segment. Our next news program
[00:03:44] will begin in an hour. Thank you for choosing BBC Persian.
[00:03:47] The head of the Iranian Alzheimer's
[00:03:53] Association recently warned that the number of patients
[00:03:57] aged 45 to 65 with Alzheimer's symptoms
[00:04:00] has increased. In the second special program on forgetfulness
[00:04:03] and dementia, we will discuss 14 proven methods
[00:04:07] for preventing dementia that are achievable
[00:04:10] for all of us. We will discuss the latest Alzheimer's
[00:04:14] treatments and their effectiveness and ask experts
[00:04:17] if Alzheimer's is hereditary. Is Alzheimer's
[00:04:21] hereditary?
[00:04:54] Before we delve into the 14 effective ways to prevent dementia
[00:04:57] and forgetfulness, let's first consider if this disease
[00:05:01] is indeed hereditary. The reality is that while Alzheimer's
[00:05:05] is more common in some families than others,
[00:05:09] it's not the case that if a parent had Alzheimer's,
[00:05:13] for example, there's a 100% or even 50% chance of inheriting
[00:05:16] the disease. However, it's true that first-degree
[00:05:19] relatives have a slightly higher chance of developing
[00:05:23] the disease. In recent years,
[00:05:27] a significant number of genetic factors that increase the risk
[00:05:31] and likelihood of developing Alzheimer's have been identified, particularly
[00:05:35] a gene called APOE, which has been extensively written
[00:05:38] about and researched. The reality is that individuals
[00:05:42] with a specific type of APOE have a higher chance compared
[00:05:46] to others who don't have that type,
[00:05:49] but not in a dramatically increased way.
[00:05:52] Regarding frontotemporal dementia, which we discussed,
[00:05:56] it's a disease that affects younger individuals. The role
[00:06:00] of genetic factors is more prominent in that disease,
[00:06:03] and perhaps around 20 to 30% of
[00:06:07] individuals inherit a gene from their family
[00:06:10] that causes the disease for them. Other types
[00:06:14] of diseases that lead to dementia don't have
[00:06:18] such a strong genetic component, with the exception
[00:06:21] of Down syndrome. Because of the specific genetic
[00:06:25] problem that individuals with Down syndrome have,
[00:06:28] it's almost guaranteed that individuals with Down syndrome
[00:06:32] will have an increased amount of substances that lead
[00:06:35] to Alzheimer's in their brains around the age of 40,
[00:06:39] and they will almost certainly show symptoms by the age of 50.
[00:07:12] are effective in prevention. It's true that genetics and age cannot
[00:07:16] be changed, but for factors related to a healthy lifestyle,
[00:07:20] things can be done.
[00:07:23] A study on 29,000 people was conducted regarding
[00:07:26] the prevention of dementia. Could you explain its findings?
[00:07:29] We estimate
[00:07:32] that about 40% of cases of onset
[00:07:35] could be preventable. Currently, millions of
[00:07:38] people worldwide live with dementia, and it is predicted
[00:07:42] that by 2050, this number will reach
[00:07:45] over 150 million. Any action that can reduce
[00:07:49] this statistic is crucial. Of course, countries
[00:07:53] have different situations based on their resources,
[00:07:56] but the potential for change is very high, and much
[00:08:00] more can be done. Most people don't even
[00:08:03] know that they can reduce their risk. A study
[00:08:07] in Britain showed that only one-third of people know
[00:08:11] that the probability
[00:08:16] It's true that there is no definitive cure for dementia,
[00:08:19] forgetfulness, and Alzheimer's, but the very good news
[00:08:23] is that according to the latest reputable studies, there
[00:08:26] are 14 things we can do to prevent
[00:08:30] or delay the onset. Experts say that if you do
[00:08:33] these 14 things, 40 to 45
[00:08:37] percent of cases of onset are either preventable or
[00:08:41] delayed, which is a lot. 40 to 45. Let's see what
[00:08:44] these 14 things are. Education in early life
[00:08:48] is very important. It alone can
[00:08:50] reduce the incidence of this brain disease by 5%
[00:08:54] globally. The better the education,
[00:08:57] the more cognitive reserve the brain has, and the brain
[00:09:01] gains greater resistance to dementia
[00:09:04] in later years. This is from early
[00:09:07] life. In the middle
[00:09:11] years and in middle age, there are things we can do.
[00:09:15] The first and most important
[00:09:21] is treating or correcting hearing loss. If all those in the world who suffer
[00:09:24] from hearing loss can treat or correct this problem,
[00:09:27] for example, with hearing aids, 7% of
[00:09:31] Alzheimer's, dementia, forgetfulness, and
[00:09:35] dementia cases globally will decrease.
[00:09:39] More research is needed to understand the mechanism
[00:09:42] of hearing loss's impact on dementia, but one
[00:09:46] possible explanation is that when you don't hear well, your
[00:09:49] social interactions are affected. Communication with others becomes
[00:09:53] more difficult, and you may be less inclined to go out.
[00:09:56] Hearing loss even affects body balance, and sometimes
[00:10:00] you fall more often. This might lead you to go out less
[00:10:03] and walk less. So, hearing loss creates a vicious
[00:10:07] cycle and thus increases the risk of dementia.
[00:10:11] According to the evidence we have so far, using hearing
[00:10:15] aids can be very beneficial and significantly reduce
[00:10:18] the risk. That's why it's very important to get our hearing
[00:10:22] checked regularly, just like our eyes. There are also
[00:10:26] free online tests. If these tests show a problem,
[00:10:30] then you can consult a specialist. You may or may not need
[00:10:33] a hearing aid. This negative view of hearing aids
[00:10:37] being clunky and ugly, or only for the elderly,
[00:10:40] is simply not true. Many of us might think
[00:10:43] it's too early to worry about our hearing in our 40s.
[00:10:47] But when I was working on a report about tinnitus,
[00:10:51] I decided to take a hearing test myself.
[00:10:55] The result surprised and saddened me deeply.
[00:11:20] Oh, these charts are very scary. The two are completely
[00:11:23] different.
[00:11:45] Here it's clear that your right ear hears all sounds.
[00:11:49] Your left ear also hears almost all frequencies except
[00:11:53] one. The fact is that
[00:11:58] many of our speech sounds are in the frequency range of 3,
[00:12:01] 4, 5, and 6 kilohertz. Sounds like "f," "s," and
[00:12:05] "th" are those high-pitched and delicate speech sounds.
[00:12:09] in the chart, meaning it suddenly
[00:12:13] goes down and then up, it's often a sign that the person
[00:12:17] has been exposed to a lot of noise for a long time,
[00:12:20] for example, due to listening to loud music or working
[00:12:23] in a noisy environment. This hearing loss never gets better.
[00:12:27] Usually, when such a chart is seen, it often means that
[00:12:31] permanent damage has been done to the inner ear. Do I need
[00:12:34] to wear a hearing aid? I don't recommend it for now,
[00:12:38] unless this hearing loss causes you problems in understanding
[00:12:42] others and socializing. If not, for now, take
[00:12:45] care of your ears and repeat the hearing test every year.
[00:12:49] Treatment for depression reduces cases by 3%,
[00:12:52] and treatment for severe brain injuries or serious
[00:12:56] head injuries, such as heading in football, which we've also
[00:13:00] had a program on before, reduces the number of cases
[00:13:04] by 3%. I also made a program about how heading
[00:13:07] the ball in football can damage the brain and lead to dementia
[00:13:11] in adulthood. I came to see Dr. Michael Gray, a senior
[00:13:15] researcher for one of the most reputable studies
[00:13:18] in this field. What do we know about the link between head
[00:13:21] injuries in football and brain diseases? First, I want to emphasize
[00:13:25] that running in football is excellent for our brain
[00:13:29] health. The problem is that if someone has repeatedly
[00:13:32] performed actions like heading the ball during their professional
[00:13:36] career, their brain will suffer more neurodegeneration
[00:13:40] after the age of 50 and certainly after
[00:13:43] 65, compared to someone who hasn't. Therefore,
[00:13:46] if we compare a professional runner with a professional
[00:13:49] footballer, we see that the footballer's brain is more
[00:13:53] damaged, and the reason is that the footballer heads the
[00:13:57] ball. Many people might think that at that age,
[00:14:01] anyone might develop dementia, but in 2019, an important
[00:14:04] study called FIELD was published, which clearly showed that
[00:14:08] professional footballers have a five times higher risk
[00:14:11] of developing dementia than an ordinary person.
[00:14:15] These risks were not observed
[00:14:16] in goalkeepers, who head the
[00:14:21] ball less often. Dr. Gray, how can a head injury cause
[00:14:26] such damage to the brain? If, as a result of a direct
[00:14:29] or even indirect blow to the head, brain function
[00:14:33] changes in the short term, we say that brain injury
[00:14:37] has occurred. It doesn't have to be a blow to the head;
[00:14:41] it could be a blow to the body, but due to the whiplash
[00:14:44] effect, the brain is damaged.
[00:14:46] Perhaps a good example is bobbleheads, where
[00:14:50] a large head sways on a slender neck.
[00:14:53] Look at this brain, which sits on top of the head.
[00:14:57] When something hits it, the brain wobbles
[00:14:59] and shakes.
[00:15:01] The skull prevents catastrophic injuries, but it doesn't
[00:15:05] prevent the brain from wobbling. The brain is not actually
[00:15:08] attached to the skull. The brain floats
[00:15:11] in the cerebrospinal fluid
[00:15:13] inside the skull.
[00:15:16] Brain tissue is like jelly in a mold;
[00:15:18] it's soft. Any impact causes this tissue
[00:15:22] to shake back and forth and also to rotate.
[00:15:26] This shaking and rotation damages the nerve fibers
[00:15:29] in the brain, i.e., axons.
[00:15:37] Are these
[00:15:45] Children are definitely more susceptible to brain injuries
[00:15:49] than adults, and there are several reasons for this. The part
[00:15:53] of the brain responsible for risk protection is not fully
[00:15:56] formed in children, nor are the neural connections
[00:16:00] of that part, nor even the white matter, which is the tissue
[00:16:03] that surrounds the nerves for risk protection. None
[00:16:07] of them are fully developed. On the other hand, the whiplash
[00:16:11] effect is greater in children because a child's head
[00:16:14] size is almost similar to an adult's, but a child
[00:16:17] does not have the neck muscles of an adult. Therefore, children
[00:16:21] cannot tolerate the whiplash effect, and this is the main
[00:16:24] cause of mechanical injury due to brain
[00:16:27] shaking. If footballers head the ball more in their
[00:16:31] youth, does it increase the severity of their Alzheimer's
[00:16:34] or Parkinson's in adulthood? We used to think that
[00:16:38] if someone suffered multiple concussions during their professional
[00:16:41] playing career, this would lead to dementia. But now
[00:16:45] we think the cause is what we call micro-concussions.
[00:16:49] These are concussions that have no clinical symptoms,
[00:16:52] meaning people don't get headaches or experience brain fog.
[00:16:56] They don't know that their brain has been damaged. But
[00:16:59] more often in training and also in competitions, with
[00:17:03] the continuous repetition of these concussions every day, every
[00:17:07] week, and for many years, these injuries accumulate.
[00:17:11] And in our opinion, it is these micro-brain shakes
[00:17:14] that lead to more severe neurodegeneration in later
[00:17:18] life. The important point is that footballers, compared
[00:17:21] to other healthy individuals in society, develop these
[00:17:25] neurodegenerative diseases at a much younger age.
[00:17:29] So we should still exercise. We should maintain the cardiovascular
[00:17:33] benefits of this exercise, but no longer head the ball.
[00:17:36] At the very least, children
[00:17:39] should not head the ball in this game. If people control
[00:17:42] their high cholesterol, again, 7% of cases
[00:17:45] of this disease in the world are either reduced
[00:17:48] or the onset is delayed to later
[00:17:52] years. If your doctor has prescribed medication
[00:17:55] to control your cholesterol, that's fine.
[00:17:59] But if they told you to lower your cholesterol by changing
[00:18:02] your lifestyle, two things were effective
[00:18:05] for me: eating two apples with skin daily.
[00:18:08] Your cholesterol was slightly high before this test.
[00:18:12] Normally, it should be less than 5,
[00:18:16] and yours was 6 millimoles per liter.
[00:18:19] But after this test, it has come down to 4.10,
[00:18:23] and the other thing was a 100% vegetarian
[00:18:27] diet, which I tried
[00:18:27] for a month.
[00:18:32] If you prevent or control diabetes,
[00:18:35] 2% of cases are reduced.
[00:18:38] Quitting smoking by 2%, controlling
[00:18:41] blood pressure by 2%,
[00:18:45] treating obesity and morbid obesity
[00:18:48] by 1%, reducing alcohol consumption
[00:18:51] by 1%, all eliminate or delay
[00:18:55] the onset of forgetfulness and dementia. Quitting smoking
[00:18:58] helps. Any time you quit smoking, it's great.
[00:19:01] At any age we quit, it reduces the risk of onset
[00:19:05] by 2%. Of course, earlier
[00:19:08] is better, but even at older ages, quitting
[00:19:11] smoking can reduce the risk of dementia.
[00:19:14] Research has shown that those who were able
[00:19:18] to consume healthy and diverse foods,
[00:19:21] such as fruits, seeds, vegetables, and some
[00:19:25] meat, fish, and grains, had a lower risk of
[00:19:28] developing dementia. Naturally, consuming
[00:19:31] excessive fats, salt, and processed
[00:19:35] foods is harmful.
[00:19:38] What about mental activities? Which are the most beneficial?
[00:19:41] Apparently, engaging in a variety of different activities, whether
[00:19:45] solving puzzles, learning a language, or playing
[00:19:49] an instrument, all of which keep the brain active,
[00:19:52] are beneficial. Especially when they are enjoyable
[00:19:56] and you regularly continue them. This helps the brain
[00:19:59] remain flexible, and even when diseases that cause
[00:20:02] dementia damage its cells, it can continue to function.
[00:20:06] Research has shown that even at old age and perhaps
[00:20:10] in the early stages of dementia, any change
[00:20:13] in lifestyle is likely beneficial,
[00:20:17] especially activities like exercise that help
[00:20:20] increase strength and motor skills. What do we
[00:20:24] know about the connection between air pollution and
[00:20:27] this disease?
[00:20:29] We still don't know exactly through what mechanism
[00:20:33] air pollution increases the risk of dementia, but
[00:20:36] it is probably due to the effect of pollutants
[00:20:40] on the cardiovascular system. Since blood
[00:20:43] vessels also reach the brain, this damage is also
[00:20:46] transmitted to the brain. Probably the same risk.
[00:20:56] In later years of life, there are three important things we need to do. The most important is to ensure we don't become socially
[00:21:00] isolated. If we maintain our social connections
[00:21:04] at that age, 5% of all cases
[00:21:08] of forgetfulness, dementia, and
[00:21:10] cognitive decline globally will either disappear
[00:21:14] or be delayed. 5%.
[00:21:17] This is very interesting.
[00:21:20] We don't exactly know why it's so important,
[00:21:24] but interaction and socializing with others,
[00:21:27] whether by phone calls, walks together,
[00:21:30] or a coffee or tea appointment, or any
[00:21:34] other social activity, contributes to both cognitive
[00:21:38] health and mental health. It's a positive cycle
[00:21:42] where all parts help each other.
[00:21:45] Another important point is that if the problem
[00:21:49] of air pollution is resolved, or if the air where we live
[00:21:53] is not polluted, then at that age alone,
[00:21:57] the incidence of this disease can be reduced by 3%.
[00:22:00] And finally, if you have vision problems
[00:22:04] and can treat them at that age, 2% of
[00:22:07] all dementia cases globally will be reduced or delayed.
[00:22:11] In total, if you do all these 14 things,
[00:22:15] you can prevent 40 to 45% of cases of this disease,
[00:22:18] which is a very large number until a definitive
[00:22:22] cure exists.
[00:22:23] Another area that is
[00:22:27] very interesting from a research perspective is the connection
[00:22:30] between sleep and the risk of dementia. There is still
[00:22:34] no clear evidence for this. This possibility
[00:22:37] has neither been confirmed nor rejected, but it is
[00:22:40] very intriguing. Considering what happens
[00:22:44] during sleep and its positive impact on brain
[00:22:47] health, if a connection exists, it wouldn't be surprising
[00:22:51] at all.
[00:22:53] It's true that these 14 factors we mentioned are things
[00:22:57] we can do to prevent or delay dementia.
[00:23:01] However, there are two points you should know. First,
[00:23:05] these diseases are not always preventable, and second,
[00:23:08] if we or one of our loved ones develops a disease
[00:23:12] under the umbrella of dementia, it's not our fault.
[00:23:15] We shouldn't blame ourselves. However, the more research
[00:23:19] is done,
[00:23:23] both about better understanding this disease and about ways
[00:23:26] to help affected individuals, Professor James Rowe,
[00:23:30] a cognitive neurology professor at Cambridge University,
[00:23:33] is very hopeful about the future of this research. This is
[00:23:36] an extraordinary period for dementia specialists. We are
[00:23:39] on the verge of a major transformation, and progress
[00:23:43] in understanding the causes of dementia, as well as in
[00:23:46] faster diagnosis and potential treatment methods, is very
[00:23:50] rapid. The speed of changes is very exciting and not
[00:23:53] even comparable to a decade ago. Recently, the news of a new
[00:23:57] blood test for diagnosing dementia has attracted
[00:24:00] a lot of attention. With new tests, changes in the body
[00:24:04] that are related to Alzheimer's, for example, can be identified
[00:24:07] with a simple blood sample. Of course, observing these
[00:24:10] changes does not necessarily mean that memory problems
[00:24:14] are definitely Alzheimer's, but it is a big step
[00:24:17] forward and makes the diagnosis process faster, simpler,
[00:24:20] cheaper, and more accessible. Are you looking for other
[00:24:24] measurable markers for Alzheimer's diagnosis? For many
[00:24:27] years, the focus has been on amyloid protein. This
[00:24:31] protein is a big part of Alzheimer's, but it may
[00:24:35] not be the most important part, and it may not be
[00:24:38] where treatments have the most efficacy. There are other
[00:24:42] harmful proteins, one of which is a protein called Tau,
[00:24:45] which plays a big role in this story. In addition,
[00:24:49] inflammation occurs in the brains of people with dementia.
[00:24:53] Some brain cells also undergo a specific type
[00:24:56] of death. So, solutions can be found. It may be possible
[00:25:00] to save those brain cells, reduce inflammation, and
[00:25:03] inhibit the Tau protein. All of these open up
[00:25:06] avenues for treatment. Treatments that are likely more effective,
[00:25:10] more practical, and more accessible, and will be realized
[00:25:14] in the next few years. What are the new treatments?
[00:25:17] In this area, there have also been enormous changes
[00:25:21] in the past couple of years. Now we have two approved
[00:25:24] treatment methods that are the beginning of this path.
[00:25:28] Although the effectiveness of these treatments is limited
[00:25:31] and they are only suitable for a small group
[00:25:35] of patients, it is considered a start. This reminds
[00:25:39] all those involved in this field and policymakers
[00:25:43] that dementia, like any other disease, is
[00:25:46] treatable if there is investment, research, clinical trials,
[00:25:50] and effective treatments are found. We will definitely
[00:25:54] make progress. These two treatments have put us at
[00:25:58] the beginning of this path. I believe that in the
[00:26:01] next 10 years, we will see a wide range of different
[00:26:05] treatments. More patients will receive treatment,
[00:26:08] and the treatments will also fundamentally be more effective
[00:26:11] and safer. But what do we know about the new
[00:26:15] Alzheimer's treatments? These drugs, Lecanemab
[00:26:19] and Donanemab, target a protein called
[00:26:22] amyloid-beta, a protein that abnormally
[00:26:25] accumulates in the brains of individuals with Alzheimer's
[00:26:29] disease. These drugs, by helping to remove these
[00:26:33] amyloid deposits in the brain, can slow down the progression
[00:26:36] of the disease to some extent. These drugs
[00:26:39] are not a definitive cure for dementia, but
[00:26:43] they may be beneficial for some individuals who
[00:26:46] are in the very early stages of Alzheimer's.
[00:26:50] By slowing down the progression,
[00:26:53] they can help them maintain their independence for
[00:26:56] a longer period and experience milder symptoms.
[00:27:00] Of course, these drugs can also have
[00:27:04] side effects such as brain swelling or small
[00:27:08] brain hemorrhages, and the patient should be regularly
[00:27:12] monitored with an MRI. Who is eligible to receive
[00:27:15] these new treatments? Only individuals in
[00:27:19] the early stages of Alzheimer's disease who have mild
[00:27:22] symptoms, and doctors must also confirm the presence
[00:27:26] of amyloid protein accumulation in the brain.
[00:27:30] This is done with a brain PET scan or a CSF test.
[00:28:02] We also collaborate very closely with computer and artificial
[00:28:05] intelligence specialists, engineers, and immunobiologists.
[00:28:09] Understanding this disease requires a very wide range
[00:28:12] of skills and expertise. For example, in the
[00:28:16] meeting you had today, what kind of help would you expect
[00:28:19] from an AI specialist? Artificial intelligence
[00:28:22] is a collection of various
[00:28:26] and capabilities, and it has numerous applications. For example,
[00:28:29] it can extract the best information from brain scans
[00:28:35] and look for indicators that help diagnose the disease
[00:28:39] or predict the patient's condition. These are indicators
[00:28:42] that are not visible to the naked eye. It can also
[00:28:45] gather more information from complex blood tests.
[00:28:49] From one blood sample, we can measure two or three thousand
[00:28:52] different biochemical substances. Each of these substances
[00:28:56] gives us a small piece of information, but individually,
[00:28:59] they are very weak. Artificial intelligence
[00:29:03] combines all these signals, like the voices of people
[00:29:05] in a crowd, to arrive at
[00:29:08] stronger messages for diagnosis. Many people ask, while
[00:29:11] we are waiting for new treatments, can supplements help?
[00:29:14] The reality is that to date, no supplement
[00:29:17] has been able to scientifically prove with strong evidence
[00:29:21] that it can either prevent dementia or slow
[00:29:24] down its progression. That's why health experts
[00:29:28] advise caution when dealing with products that make
[00:29:31] big and definitive claims, because it's
[00:29:35] very unlikely that they have sufficient scientific backing.
[00:29:39] The incidence of dementia diseases, including Alzheimer's
[00:29:43] and forgetfulness, is increasing all
[00:29:45] over the world, and this is concerning. But
[00:29:48] let's remember that almost half of
[00:29:52] dementia cases may be preventable.
[00:29:55] It's true that controlling some factors like air pollution
[00:29:59] is not in our hands, but there are many
[00:30:02] things we can do, from paying attention
[00:30:06] to our hearing Healthy eating,
[00:30:09] exercise, keeping your mind active, and maintaining
[00:30:12] social relationships are things that reputable research shows
[00:30:16] can really help reduce the risk of developing forgetfulness,
[00:30:19] Alzheimer's, and dementia. I hope this
[00:30:23] program was useful for you. The full program has just been
[00:30:26] uploaded to YouTube. If you think it would be helpful for someone, I would be very grateful if
[00:30:30] you could send them the link. I will also upload short
