Entire Body System
- Falling
Injuries from falls. People with Alzheimer's may become disoriented, increasing their risk of falls. Falls can lead to fractures. In addition, falls are a common cause of serious head injuries, such as bleeding in the brain. [alzheimersreadingroom.com]
People with this type of dementia also experience visual hallucinations and have trouble falling asleep at night or fall asleep unexpectedly during the day. They also might faint or become lost or disoriented. [healthline.com]

Alzheimer’s Disease and Diet Early evidence that was largely forgotten indicated that there were dietary associations with AD, much as there are with heart disease and diabetes. [thediabetescouncil.com]
Alzheimer’s Disease (AD) is now as epidemic as heart disease, diabetes or cancer in the U.S., except Alzheimer’s is always fatal. [smallfootprintfamily.com]

Musculoskeletal
- Muscle Twitch
A form of muscle twitching and spasm, called myoclonus, is also more common in early-onset Alzheimer's. Late-onset Alzheimer's. This is the most common form of the disease, which happens to people age 65 and older. It may or may not run in families. [webmd.com]
People with early Alzheimer's are more likely to develop muscle twitching and spasms. They may be more active and physically fit than people with late-onset Alzheimer's disease, but decline at a faster rate, according to the Mayo Clinic. [usatoday.com]
Psychiatrical
- Anger
If you’ve been diagnosed with Alzheimer’s, you may feel anger, be scared about what the future will bring, uncertain about how your memory will change—or all of these emotions at once. These feelings are all normal. [helpguide.org]
Instead, this subtype of the disease tends to alter behavior, causing uncontrollable anger, visual impairments, speech problems, and the feeling that your limbs do not belong to you. [articles.mercola.com]

Alzheimer’s disease vs. mild cognitive impairment (MCI) Considered by some to be an intermediate stage between normal aging and the onset of Alzheimer’s disease, mild cognitive impairment (MCI) is characterized by persistent forgetfulness, but lacks many [helpguide.org]
It's often termed "mild cognitive impairment" (MCI) as the symptoms are not severe enough to be diagnosed as dementia. You might not notice these symptoms if you have them, and family and friends may not notice or take them seriously for some time. [nhs.uk]
Mystified scientists When they found that the woman had the Presenilin 1 mutation, but had not yet even developed a pre-Alzheimer’s condition called mild cognitive impairment, the scientists were mystified. [irishtimes.com]

A number of drugs exist, which can help alleviate certain symptoms such as agitation, anxiety, depression, hallucinations, confusion and insomnia. [alzheimer-europe.org]
Doctors can also provide recommendations and medications to help a person who is experiencing related health issues, such as insomnia, which may be contributing to memory problems. [medicalnewstoday.com]

Treatment can also improve your quality of life and help treat symptoms. Talk with your doctor about your treatment options. A study identified several factors that affect a person’s life expectancy. [healthline.com]
Treatment of EOAD Treatment of Alzheimer's disease is largely supportive. Treatment for aggression, depression, seizure activity, sleep disturbances as well as any hallucinations the person may experience are all managed on an individual basis. [disabled-world.com]
Prognosis
Prognosis The disease is progressive; patients have deterioration in their behavior, cognition, and ability to perform activities of daily living. At an advanced stage, patients are confined to bed. [orpha.net]
According to the MMSE model, the use of antipsychotics in participants with LOAD implied worse prognosis. [alzres.biomedcentral.com]
Outlook (Prognosis) How quickly AD gets worse is different for each person. If AD develops quickly, it is more likely to worsen quickly. [ufhealth.org]
Etiology

There may be a further genetic factor involved in the etiology of autosomal dominant early onset AD. Received February 26, 2002. Accepted September 26, 2002. [n.neurology.org]
Etiology EOAD is the consequence of either PSEN1 mutations (69%), APP mutations (13%), or APP duplication (7,5%), and exceptionally of PSEN2 mutations (2%). [orpha.net]
It can be differentiated from postencephalitic syndrome (F07.1) and postconcussional syndrome (F07.2) by its different etiology, more restricted range of generally milder symptoms, and usually shorter duration. [apps.who.int]
Epidemiology

Summary Epidemiology EOAD represents less than 1% of all cases of AD. Clinical description Initial findings of EOAD are mainly disorders of episodic memory or changes in behavior. [orpha.net]
Overall, the hypothesis that Alzheimer’s is a metabolic disease remains preliminary and supported by limited evidence in humans beyond epidemiological correlations. [crossfit.com]

Pathophysiology In 1984, Glenner first proposed that cerebral A drives all subsequent pathology [44]. [hindawi.com]
Prevention
In the case of vascular dementia, brain cells die due to lack of oxygen, preventing brain cells from communicating with each other. [alzheimer.ca]
Prevention / risk reduction There are no proven ways to prevent the development of Alzheimer's disease. However, there is epidemiological evidence to suggest that leading a healthy lifestyle can reduce the risk of Alzheimer's disease. [southerncross.co.nz]
