What does Alzheimer's Disease really do to your brain? ⬇️
Alzheimer's disease is a progressive brain disorder and a form of dementia that impacts memory, thinking and behavior. As symptoms grow more severe, the disease can seriously affect a person's ability to perform tasks that would otherwise be deemed routine. There is currently no cure for Alzheimer's, but there are medications available that can temporarily delay symptoms.
However, while many people argue that the amyloid plaques are the cause of the disease, others say they are just a biomarker for the disease showing that other physiological processes are wrong and they cause the disease, Carson said. The continued loss of connections between nerve cells damages them to the point that they can no longer function properly in the parts of the brain affecting memory, and the nerve cells eventually die. As more nerve cells die, parts of the brain that control reasoning, language and thinking skills are also affected, and brain tissue begins to shrink.
Early-onset Alzheimer's affects people in the mid 30s to mid 60s, and some forms may be inherited. But early-onset disease represents less than 10% of all people with the disorder, according to the National Institute on Aging . Late-onset Alzheimer's is the more common form of the disease, and its first symptoms may appear after age 65.
Alzheimer's also causes mood and behavior symptoms, including depression, sleeplessness, distrusting others, hallucinations and delusions, loss of inhibitions, mood swings, wandering and pacing and anger or aggression. "Sometimes, more robust and specific tests are performed by a memory clinic, which can involve several hours of testing," Coulson said."Sometimes an MRI brain scan is performed to look for which parts of the brain are degenerating, or a CT scan to look for vascular changes."
