• 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]

• Visual Impairment

  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]

  Hearing and visual impairment among older persons with dementia could lead to more delusions and visual hallucinations, respectively [49]. [alzres.biomedcentral.com]

• 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]

• Suggestibility

  Current evidence suggests hyperinsulinemia, and/or insulin resistance specifically, is most strongly linked to increased risk of Alzheimer’s. [crossfit.com]

  Animal studies suggest disrupted sleep may result in increased amyloid accumulation. [theconversation.com]

  This study suggests individuals with the APOE-4 gene will develop Alzheimer’s disease at an earlier age. Another study has suggested that there is a genetic cause for the sporadic form of Alzheimer’s disease. [rarediseases.org]

  Findings of this case study as published in Nature Medicine suggest that two copies of the APOE3ch variant, named after Christchurch, New Zealand where it was first identified, may protect against Alzheimer's. [sciencedaily.com]

  This may sometimes be called aphasia. People can have difficulty recognising words and objects and judging speed or distance. When visual problems are a major symptom, the disease may be called posterior cortical atrophy. [alzheimersresearchuk.org]

  These include behavioral variant frontotemporal dementia (FTD), semantic dementia, primary progressive aphasia, and FTD-motor neuron disease. In about 15 to 40 percent of people, a genetic (hereditary) cause can be identified. [depts.washington.edu]

  Mendez (see Further Reading below) describes how EOAD can present atypically, and he groups these together as “Type 2 AD”: Some people with EOAD show difficulty finding words, which could look like a condition called aphasia (the loss of ability to understand [brightfocus.org]

Other treatments that may play a role in slowing the progress of early-onset Alzheimer disease include physical activity, cardiovascular and diabetes treatments, antioxidants, and cognitive training. [hopkinsmedicine.org]

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 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]

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]

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]
