Complications Of Alzheimers Disease

Mayo Clinic Researchers Find Gene That Is Common Cause of ALS and Frontotemporal Dementia

In advanced stages of Alzheimers disease, complications from severe loss of brain function can include dehydration, malnutrition, or infection.

One common complication is difficulty swallowing , which can result in food or drink being aspirated into the lungs, potentially causing pneumonia. Pneumonia is a common cause of death for people with severe Alzheimers, notes the Mayo Clinic.

Is Alzheimers Disease Hereditary

Family history is a strong Alzheimers disease risk factor, meaning that if you have a first-degree relative such as a parent or sibling with the disease you are more likely to develop it yourself.

But that doesnt mean that Alzheimers disease is hereditary. Researchers believe that genes do not directly cause Alzheimers except in an estimated 1 percent of all cases involving gene mutations passed directly from parent to child.

If youve inherited one of three gene mutations from either your mother or father, you have a very high probability of developing a highly uncommon form of Alzheimers called familial early-onset.

This is not a common condition: Scientists have been able to identify these mutations in only 500 families around the world.

For the vast majority of people, certain genes increase the risk of Alzheimers disease but do not guarantee it.

Many people with these genes will never develop Alzheimers, because lifestyle and environment also play a role.

Scientists are studying the complex interactions between all these factors to understand Alzheimers disease causes and to learn whether its possible to keep them at bay.

Why Isnt There A Cure For Hiv

The reason why it is so difficult to cure HIV is that once HIV infects a persons body, it integrates into the host genome of several cell types. Those cells then hide in any of the lymphoid tissue, such as the lymph nodes, the liver and the spleen. And they lay there as what we call latent or hiding, as long as the person is on HIV therapy. Anytime a virus does leave a cell, it gets taken care of by HIV therapy. But if the infected individual stops the HIV therapy, that latent virus will come back. To cure HIV, you have to eliminate those hiding viruses in the cells or that latent viral reservoir, which is the term. There are many ways you can approach eliminating the reservoir.

Genetic Testing: Apoe Won’t Tell You If You Will Get Alzheimer’s Disease

As a psychologist, you learn not to tell people at a dinner party what you do for a living unless you want to jokingly/not jokingly be asked if you are trying to psychoanalyze everyone. Most of the time it is easier to say you specialize in dementia research or care, and I don’t mind hearing the stories people tell me. However, a few years ago, the conversation took an unexpected turn while talking to a salesperson. The young woman, likely in her 30s or 40s, had gotten commercially available genetic testing, which came back saying she had the APOE4 double allele, and thus was going to get Alzheimer’s disease. She became tearful telling me, took the news from the commercial company as absolute fact, and asked what she should do to prepare.

Now, she wasn’t my patient – in fact, I was her client! – but I reassured her that genetic testing was not the entire picture, and I did not believe it was accurate that she had the almost certain fate of having Alzheimer’s disease one day. I told her to talk to her doctor if she was worried. I don’t know what happened from there on her end. I will tell you I was surprised and angry that a company was just casually telling folks about genetic risk for serious diseases that may or may not even be accurate.

This recently published article by JAMA Network , does a nice job of presenting these facts in a clear way.

What Are The Signs Of Alzheimer’s Disease

Mayo Clinic on Alzheimer

Scientists continue to unravel the complex brain changes involved in the onset and progression of Alzheimers disease. It seems likely that damage to the brain starts a decade or more before memory and other cognitive problems appear. During this preclinical stage of Alzheimers disease, people seem to be symptom-free, but toxic changes are taking place in the brain.

Damage occurring in the brain of someone with Alzheimers disease begins to show itself in very early clinical signs and symptoms. For most people with Alzheimersthose who have the late-onset varietysymptoms first appear in their mid-60s. Signs of early-onset Alzheimers begin between a persons 30s and mid-60s.

The first symptoms of Alzheimers vary from person to person. Memory problems are typically one of the first signs of cognitive impairment related to Alzheimers disease. Decline in non-memory aspects of cognition, such as word-finding, vision/spatial issues, and impaired reasoning or judgment, may also signal the very early stages of Alzheimers disease. And some people may be diagnosed with mild cognitive impairment. As the disease progresses, people experience greater memory loss and other cognitive difficulties.

Alzheimers disease progresses in several stages: preclinical, mild , moderate, and severe .

Although no cure for posterior cortical atrophy exists, several medications, as well as many non-pharmaceutical approaches, can potentially improve daily functioning and quality of life. Patients with posterior cortical atrophy can often benefit from physical and occupational therapy.

Cholinesterase inhibitors approved for Alzheimers disease, like donepezil , rivastigmine and galantamine , can help the symptoms of PCA by boosting the function of brain cells to compensate for damage caused by Alzheimers disease.

Patients experiencing depression, irritability, frustration and a loss of self-confidence may benefit from antidepressant medication.

Stage : Moderate Dementia

When a person has moderate dementia due to Alzheimers disease, they become increasingly confused and forgetful. They may need help with daily tasks and with looking after themselves. This is the longest stage and often lasts around 24 years.

Symptoms of moderate dementia due to Alzheimers disease include:

  • losing track of the location and forgetting the way, even in familiar places
  • wandering in search of surroundings that feel more familiar
  • failing to recall the day of the week or the season
  • confusing family members and close friends or mistaking strangers for family
  • forgetting personal information, such as their address
  • repeating favorite memories or making up stories to fill memory gaps
  • needing help deciding what to wear for the weather or season
  • needing assistance with bathing and grooming
  • occasionally losing control of the bladder or bowel
  • becoming unduly suspicious of friends and family
  • seeing or hearing things that are not there
  • becoming restless or agitated
  • having physical outbursts, which may be aggressive

As Alzheimers progresses, a person may start to feel more restless toward evening and have difficulty sleeping. This is sometimes called sundowners syndrome.

During this stage, physical and mental functioning continue to decline.

If a person has severe dementia during the later stages of Alzheimers disease, they might:

Other common causes of death among people with Alzheimers disease include dehydration, malnutrition, and other infections.

What Are The 7 Stages Of Alzheimers Disease

There are a number of different ways to describe the progression of Alzheimers disease. Although many experts use just three overall terms mild, moderate, and severe one commonly used guideline breaks these categories down further into seven stages, according to the Fisher Center for Alzheimer’s Research:

  • Stage 1: Normal
  • Stage 2: Normal aged forgetfulness
  • Stage 3: Mild cognitive impairment
  • Stage 4: Mild Alzheimers disease
  • Stage 5: Moderate Alzheimers disease
  • Stage 6: Moderately severe Alzheimers disease
  • Stage 7: Severe Alzheimers disease

Related Conditions And Causes Of Alzheimers Disease

It is very common for people with Alzheimers disease to simultaneously experience brain abnormalities related to other types of dementia, a condition called mixed dementia.

Other types of dementia include:

  • Vascular Dementia The most prevalent type of mixed dementia involves Alzheimers combined with vascular dementia, in which brain cells are deprived of essential nutrients and oxygen because of conditions that block or reduce blood flow to the brain.
  • Lewy Body Dementia. People with Alzheimers may also simultaneously experience Lewy body dementia, a disease marked by abnormal clumps of the protein alpha-synuclein in brain cells.

Some people may simultaneously experience brain changes related to all three conditions Alzheimers, vascular dementia, and Lewy body dementia according to the Alzheimer’s Association.

Other Rare Types Of Dementia

Other rare types of dementia that can be passed down through the family include Huntingtons disease and Familial Prion disease. These diseases have a 50/50 chance of being passed on because they are caused by a single faulty dominant gene.

This means that, if you inherit a healthy gene from one parent and a faulty gene from the other parent, the faulty one will always be the one that is used because its the dominant gene.

For more information, care and support services, please refer to the Huntingtons Disease Association or the National Prion Clinic at UCL.

What Are The Signs & Symptoms Of Alzheimers Disease

Early signs and symptoms of Alzheimers disease vary from person to person. Initially, you may forget events and incidents with mild confusion. But with time Alzheimers disease worsens to frequent memory loss of most recent events, in spite of regular reminders. Difficulty in conversation and judgment is also observed in patients with Alzheimers disease. The most common signs include

  • Behavioral changes: The personality and behavior of an individual with the disease may change abnormally and they may experience
  • Apathy
  • Social withdrawal
  • Wandering
  • Concentration and reasoning: Patients lose the power to concentrate and think especially numeric. They experience difficulty in performing transactions they are also frequently confused in various situations.
  • Individuals with Alzheimers disease may experience difficulty in decision making. Patients would always think that they are right even when it is evident that he/she is wrong.
  • Language: Patients with Alzheimers disease have a problem in communicating as they are confused with the language used.

Prevention Of Alzheimers Disease

Mayo Clinic on Alzheimer

Can a healthy lifestyle reduce Alzheimers risk? A growing body of research suggests it can.

For instance, a study published in July 2019 in the Journal of the American Medical Association found that people who were genetically predisposed to develop Alzheimers reduced their risk by 32 percent by pursuing a healthy lifestyle that involved:

  • Not smoking

Alzheimers And The Brain

Alzheimers disease is named for a German psychiatrist and neuropathologist named Alois Alzheimer. While conducting a postmortem in 1906, the doctor noticed abnormalities in the brain of a woman with a mysterious illness that caused memory loss, language problems, unpredictable behavior, and ultimately death.

The womans brain, Alzheimer reported, had many abnormal protein clumps as well as tangled bundles of fibers . Those clumps and tangles are today considered the hallmarks of Alzheimers disease.

Alzheimers disease causes nerve cells to stop functioning, lose their connections with other neurons, and die.

Typically, the damage first affects the parts of the brain that form memories. Eventually neurons in other areas of the brain also begin to die, causing the brain to shrink.

Mayo Clinic Investigators Begin New Projects To Understand The Genetic Risk Of Alzheimer’s Disease

The apolipoprotein E gene is known to play a role in the risk of developing Alzheimer’s disease. Some forms of ApoE convey greater risk of getting the disease, while other forms of the gene appear to be protective against the disease. The gene has far-reaching effects, including a role in age-related cognitive decline and vascular cognitive impairment.

Led by Dr. Goujun Bu, a Professor and Chair of the Department of Neuroscience at Mayo Clinic Florida, investigators from the Mayo Clinic Alzheimer’s Disease Research Center are collaborating and sharing information with colleagues at Washington University in St. Louis and Icahn School of Medicine at Mount Sinai in New York to open up new research projects that will better understand the role of ApoE in disease. According to Dr. Goujun, “While significant progress has been made in identifying ApoE pathways in the brain, there are critical gaps in knowledge to guide therapeutic strategies.” The goal of this work is to identify individualized therapies that will target ApoE and prevent and perhaps cure Alzheimer’s disease.

Can Alzheimers Disease Be Inherited

In the vast majority of cases , Alzheimers disease is not inherited.

The most important risk factor for Alzheimer’s disease is age. Because Alzheimer’s disease is so common in people in their late 70s and 80s, having a parent or grandparent with Alzheimer’s disease at this age does not change your risk compared to the rest of the population.

However, if somebody has developed Alzheimers disease at an earlier age there is a greater chance that it may be a type of Alzheimers disease that can be passed on.

Stage : Moderately Severe Decline

During the fifth stage of Alzheimers, people begin to need help with many day-to-day activities. People in stage five of the disease may experience:

  • Difficulty dressing appropriately
  • Inability to recall simple details about themselves such as their own phone number
  • Significant confusion

On the other hand, people in stage five maintain functionality. They typically can still bathe and toilet independently. They also usually still know their family members and some detail about their personal histories, especially their childhood and youth.

Can Alzheimer’s Disease Be Prevented

As the exact cause of Alzheimer’s disease is not clear, there’s no known way to prevent the condition.

But there are things you can do that may reduce your risk or delay the onset of dementia, such as:

These measures have other health benefits, such as lowering your risk of cardiovascular disease and improving your overall mental health.

Stage : Mild Cognitive Impairment

Mild cognitive impairment often occurs before the more severe decline of dementia. Some 1218% of people aged 60 years or older have MCI, but not all will develop dementia. According to the National Institute on Aging, around 1020% of people over the age of 65 with MCI will develop dementia within any 1-year period.

A person with MCI may notice subtle changes in their thinking and ability to remember things. They may have a sense of brain fog and find it hard to recollect recent events. These issues are not severe enough to cause problems with day-to-day life or usual activities, but loved ones may start to notice changes.

Many people become more forgetful with age or take longer to think of a word or remember a name. However, significant challenges with these tasks could be a sign of MCI.

Symptoms of MCI include:

Scientists have identified a condition called mild cognitive impairment that for some people is a harbinger of Alzheimers dementia. MCI involves problems with memory or mental function that are noticeable to the person affected but not serious enough to interfere with everyday life.

Men and women who have MCI may be at higher risk of developing Alzheimers or other forms of dementia than individuals who dont. But MCI doesnt always progress some people even get their cognitive abilities back. Researchers are trying to figure out why, notes the Mayo Clinic.
