Amyloid reduces your heart's ability to fill with blood between heartbeats. Less blood is pumped with each beat, and you may experience shortness of breath. If amyloidosis affects your heart's electrical system, your heart rhythm may be disturbed. Amyloid-related heart problems can become life-threatening.
AL amyloidosis is caused by an abnormality in certain cells found in the bone marrow, called plasma cells. The abnormal plasma cells produce abnormal forms of light chain proteins, which enter the bloodstream and can form amyloid deposits.
Amyloidosis has a poor prognosis, and the median survival without treatment is only 13 months. Cardiac involvement has the worst prognosis and results in death in about 6 months after onset of congestive heart failure. Only 5% of the patients with primary amyloidosis survive beyond 10 years.
“A generation ago, a diagnosis of AL amyloidosis often was a death sentence, particularly when it involved the heart, but in the last 10 years treatments have improved by leaps and bounds so we can now give very effective treatments to many patients with the disease,” Witteles says.
However, the amyloid buildup in the brain can also affect the blood vessels, making them fragile and more likely to bleed. This results in bleeding in the brain, which is often referred to as hemorrhagic stroke or intracerebral hemorrhage.

TFNEs, also called amyloid spells, occur commonly in CAA as brief, recurrent, stereotypical episodes including both positive seizure-like and negative TIA-like phenomena. CAA is characterized by progressive deposition of amyloid-β in cortical and leptomeningeal vessel walls.
There are two well-established ways to determine if beta-amyloid is in the brain. One measures the amount of beta-amyloid present in cerebrospinal fluid, the fluid that surrounds the brain and spine, through a spinal tap. The other uses a PET brain scan to produce images of beta-amyloid on the brain.
While the presence of amyloid plaques in the brain is considered as being characteristic of Alzheimer's, some studies have shown that large amounts of amyloid plaques were present in healthy, non-demented individuals.
The term "sundowning" refers to a state of confusion occurring in the late afternoon and spanning into the night. Sundowning can cause a variety of behaviors, such as confusion, anxiety, aggression or ignoring directions. Sundowning can also lead to pacing or wandering.

Life expectancy is less if the person is diagnosed in their 80s or 90s. A few people with Alzheimer's live for longer, sometimes for 15 or even 20 years.
Many people affected by dementia are concerned that they may inherit or pass on dementia. The majority of dementia is not inherited by children and grandchildren. In rarer types of dementia there may be a strong genetic link, but these are only a tiny proportion of overall cases of dementia.
The middle stages of dementia are when anger and aggression are most likely to start occurring as symptoms, along with other worrying habits like wandering, hoarding, and compulsive behaviors that may seem unusual.
The 50% survival time in men was 4.3 years (95% CI, 2.4-6.8 years) in mild dementia, 2.8 years (95% CI, 1.5-3.5 years) in moderate dementia, and 1.4 years (95% CI, 0.7-1.8 years) in severe dementia, and in women, 5.0 years (95% CI, 4.5-6.3 years) in mild dementia, 2.8 years (95% CI, 1.8-3.8 years) in moderate dementia, ...
When most people hear the word dementia, they think of memory loss. And it does often start by affecting the short-term memory. Someone with dementia might repeat themselves and have problems recalling things that happened recently.
In the earlier stages, memory loss and confusion may be mild. The person with dementia may be aware of — and frustrated by — the changes taking place, such as difficulty recalling recent events, making decisions or processing what was said by others.
