Moderate Dementia Or Moderately Severe Decline
Stage 5 lasts about 1 1/2 years and requires a lot of support. Those who dont have enough support often experience feelings of anger and suspicion.
People in this stage will remember their own names and close family members, but major events, weather conditions, or their current address can be difficult to recall. Theyll also show some confusion regarding time or place and have difficulty counting backward.
Caregiver support: People will need assistance with daily tasks and can no longer live independently. Personal hygiene and eating wont be an issue yet, but they may have trouble picking the right clothing for the weather or taking care of finances.
Drugs Approved By The Fda
To date, only a total of five drugs developed to improve the symptoms of Alzheimer’s disease have been approved by the FDA. It is important to note that a new drug, Namzaric was approved in 2014. The five drugs function by two different mechanisms. One is cholinesterase inhibition, which delays Alzheimer’s disease by blocking hydrolysis of the critical neurotransmitter acetylcholine. This category of drugs includes donepezil ,, approved in 1996 rivastigmine ,, approved in 2000 and galantamine , approved in 2001. The other one is memantine , approved in 2003, a non-competitive N-methyl-D-aspartate channel blocker that reduces the activity of the neurotransmitter glutamate, which plays an important role in learning and memory by binding to the NMDA receptor. Memantine can inhibit the prolonged influx of Ca2+ ions, particularly from extrasynaptic receptors, that forms the basis of neuronal excitotoxicity. It is an option for the management of patients with moderate to severe Alzheimer’s disease. Namzaric is a combination of the two drugs to reduce the levels of both acetylcholine and glutamate .

Can Dementia Be Prevented
Although dementia cannot be prevented, living a health-focused life might influence risk factors for certain types of dementia. Keeping blood vessels clear of cholesterol buildup, maintaining normal blood pressure, controlling blood sugar, staying at a healthy weight basically, staying as healthy as one can can keep the brain fueled with the oxygen and nutrients it needs to function at its highest possible level. Specific healthful steps you can take include:
- Follow a Mediterranean diet, which is one filled with whole grains, vegetables, fruits, fish and shellfish, nuts, beans, olive oil and only limited amounts of red meats.
- Exercise. Get at least 30 minutes of exercise most days of the week.
- Keep your brain engaged. Solve puzzles, play word games, and try other mentally stimulating activities. These activities may delay the start of dementia.
- Stay socially active. Interact with people discuss current events keep your mind, heart, and soul engaged.

What Causes Beta Amyloid Plaques
Beta amyloid molecules are initially found in very small strands that can dissolve in the fluid between cells, which will be washed out of the brain. However, the enzyme that cuts APP into beta amyloid is not very precise and can also result in slightly larger strands that do not dissolve. The longer strands are very sticky at the level of individual molecules and start the process of clumping into the deposits referred to as plaques.

Medications For Cognitive Symptoms
No disease-modifying drugs are available for Alzheimers disease, but some options may reduce the symptoms and help improve quality of life.
Drugs called cholinesterase inhibitors can ease cognitive symptoms, including memory loss, confusion, altered thought processes, and judgment problems. They improve neural communication across the brain and slow the progress of these symptoms.
Three common drugs with Food and Drug Administration approval to treat these symptoms of Alzheimers disease are:
- donepezil , to treat all stages
- galantamine , to treat mild-to-moderate stages
- rivastigmine , to treat mild-to-moderate stages
Another drug, called memantine , has approval to treat moderate-to-severe Alzheimers disease. A combination of memantine and donepezil is also available.

Facts About Alzheimer Disease
Alzheimer disease is becoming more common as the general population gets older and lives longer. Alzheimer disease usually affects people older than 65. A small number of people have early-onset Alzheimer disease, which starts when they are in their 30s or 40s.
People live for an average of 8 years after their symptoms appear. But the disease can progress quickly in some people and slowly in others. Some people live as long as 20 years with the disease.
No one knows what causes Alzheimer disease. Genes, environment, lifestyle, and overall health may all play a role.
Emotion And Behavior Treatments
The emotional and behavioral changes linked with Alzheimers disease can be challenging to manage. People may increasingly experience irritability, anxiety, depression, restlessness, sleep problems, and other difficulties.
Treating the underlying causes of these changes can be helpful. Some may be side effects of medications, discomfort from other medical conditions, or problems with hearing or vision.
Identifying what triggered these behaviors and avoiding or changing these things can help people deal with the changes. Triggers may include changing environments, new caregivers, or being asked to bathe or change clothes.
It is often possible to change the environment to resolve obstacles and boost the persons comfort, security, and peace of mind.
The Alzheimers Association offer a list of helpful coping tips for caregivers.
In some cases, a doctor may recommend medications for these symptoms, such as:
- antidepressants, for low mood
develops due to the death of brain cells. It is a neurodegenerative condition, which means that the brain cell death happens over time.
In a person with Alzheimers, the brain tissue has fewer and fewer nerve cells and connections, and tiny deposits, known as plaques and tangles, build up on the nerve tissue.
Plaques develop between the dying brain cells. They are made from a protein known as beta-amyloid. The tangles, meanwhile, occur within the nerve cells. They are made from another protein, called tau.

How Many Americans Have Alzheimers Disease
Estimates vary, but experts suggest that more than 6 million Americans age 65 and older may have Alzheimers. Many more under age 65 also have the disease. Unless Alzheimer’s can be effectively treated or prevented, the number of people with it will increase significantly if current population trends continue. This is because increasing age is the most important known risk factor for Alzheimers disease.
Neurofibrillary Tangles And Neuropil Threads
Neurofibrillary Tangles. Neurofibrillary tangles develop from intracellular pre-tangles containing misfolded tau and small tau aggregates to mature NFTs containing bundles of cross-linked tau filaments before the neuron dies and an extracellular ghost tangle remains. Silver staining and Thioflavin S capture many mature tangles and some pre-tangles along with amyloid plaques and tau neuropil threads. Development of NFTS from the pre-tangles is more easily visualized using tau immunohistochemistry . This allows the mis-localized somal tau to be distinguished readily from the bundles of PHFs in NFTS in addition to the neuropil threads that can also be pronounced . The scale bars are 40m

Gene Discovery May Explain Why More Women Get Alzheimer’s Disease
Scientists have identified a gene that appears to increase the risk of Alzheimer’s in women, providing a potential new clue as to why more women than men are diagnosed with the disease.
The gene, O6-Methylguanine-DNA-methyltransferase, or MGMT, plays an important role in how the body repairs damage to DNA in both men and women. But researchers did not find an association between MGMT and Alzheimer’s in men.
“It’s a female-specific finding — perhaps one of the strongest associations of a genetic risk factor for Alzheimer’s in women,” said senior study coauthor Lindsay Farrer, chief of biomedical genetics at Boston University School of Medicine.
Two-thirds of the 6.5 million Americans currently living with the devastating brain disease are women, according to the Alzheimer’s Association. It’s a trend that holds true worldwide.
“Women, due to unique genetic risk factors like APOE 4 and MGMT, and sex-specific risk factors like the sudden reduction in estrogen during the peri-menopause transition, may be in the fast-lane toward the disease, while men are sitting in traffic,” said Dr. Richard Isaacson, director of the Alzheimer’s Prevention Clinic at Florida Atlantic University’s Schmidt College of Medicine, who was not involved in the study.
The APOE 4 gene is considered the strongest risk factor for the future development of Alzheimer’s in people over the age of 65, which is “especially true for women, who are more impacted by APOE 4 than men,” Isaacson said.

Dementia Caused By Huntingtons Disease
Huntingtons disease is an inherited degenerative brain disease that affects the mind and body. It usually appears between the ages of 30 and 50, and is characterised by intellectual decline and irregular involuntary movement of the limbs or facial muscles. Other symptoms include personality change, memory disturbance, slurred speech, impaired judgement and psychiatric problems.There is no treatment available to stop the progression of this disease, but medication can control movement disorders and psychiatric symptoms. Dementia occurs in the majority of people with Huntingtons disease.
Problems With The Amyloid Hypothesis
To investigate the pathogenesis of AD, a number of genetically modified mouse models were produced in which A is deposited in the brain. However, although senile plaques are formed in these mice, NFT formation and nerve cell death have not been observed . This suggested that extracellular accumulation of A fibrils is not intrinsically cytotoxic, and also that A does not induce tau accumulation. As A is a normal metabolic product of APP and is not itself toxic under normal physiological conditions, the idea developed that A oligomers were the key toxic agents.
Recent advances in amyloid imaging have made it possible to observe A amyloid accumulation in the patient’s brain. As a result, it has been found that there are many normal patients with amyloid deposits, and also AD patients with very few amyloid deposits . Further, in the brain of elderly non-demented patients, the distribution of senile plaques is sometimes as extensive as that of dementia patients . This suggests that A amyloid deposition is a phenomenon of aging, and has no direct relation with the onset of AD.
Taking these facts into account, it appears that neurodegeneration/neuronal loss and amyloid deposition are independent, unrelated phenomena , contrary to the amyloid hypothesis.

What Is Alzheimer’s Disease
Alzheimers disease is a brain disorder that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks. In most people with the disease those with the late-onset type symptoms first appear in their mid-60s. Early-onset Alzheimers occurs between a persons 30s and mid-60s and is very rare. Alzheimers disease is the most common cause of dementia among older adults.
The disease is named after Dr. Alois Alzheimer. In 1906, Dr. Alzheimer noticed changes in the brain tissue of a woman who had died of an unusual mental illness. Her symptoms included memory loss, language problems, and unpredictable behavior. After she died, he examined her brain and found many abnormal clumps and tangled bundles of fibers .
These plaques and tangles in the brain are still considered some of the main features of Alzheimers disease. Another feature is the loss of connections between nerve cells in the brain. Neurons transmit messages between different parts of the brain, and from the brain to muscles and organs in the body. Many other complex brain changes are thought to play a role in Alzheimers, too.
This damage initially takes place in parts of the brain involved in memory, including the entorhinal cortex and hippocampus. It later affects areas in the cerebral cortex, such as those responsible for language, reasoning, and social behavior. Eventually, many other areas of the brain are damaged.
Ad Risk Factors Apoe4 And Trem2
Apolipoprotein E is one of the major apolipoproteins . The ApoE gene has three alleles, 2, 3, and 4, corresponding to isoforms E2, E3, and E4, respectively. In the central nervous system, ApoE produced and secreted by astrocytes and microglia binds to lipoprotein and is taken up into nerve cells via the ApoE receptor during the developmental stage of the central nervous system and the repair period after neuronal damage.

Support For Family And Friends
Currently, many people living with Alzheimers disease are cared for at home by family members. Caregiving can have positive aspects for the caregiver as well as the person being cared for. It may bring personal fulfillment to the caregiver, such as satisfaction from helping a family member or friend, and lead to the development of new skills and improved family relationships.
Although most people willingly provide care to their loved ones and friends, caring for a person with Alzheimers disease at home can be a difficult task and may become overwhelming at times. Each day brings new challenges as the caregiver copes with changing levels of ability and new patterns of behavior. As the disease gets worse, people living with Alzheimers disease often need more intensive care.
