Senile Dementia or Dementia

Signs or Symptoms

Symptoms usually appear after the age of 65. The most common Alzheimers symptoms are: Memory loss, trouble with planning and problem solving, difficulty in completing a simple task such as taking the garbage out. One might have trouble remembering the time or place they are in, have trouble with remembering simple words or phrases, and have poor judgment. A huge change in a persons life is a change in personality. Changes in personality may result in chaotic behavior, rude or mean comments, and a dazed state of mind.


If a family member or ancestor has had the disease, then a person belonging to the same blood related family is a candidate for the disease. It is very uncommon for a person to develop Alzheimers without having a family history of the disease, but there are some cases that have developed in the world with the same circumstances.

Prenatal Tests & Childcare

There are currently no prenatal tests for the disorder. A person must be a live to be tested for the Alzheimer's gene. A person or child with early onset Alzheimers will either live with a relative who cares for them, or they will live in an assisted living home specifically for Alzheimers affected patients. The person will need 24/7 care, and need to be watched very carefully. The younger a person is, the more danger they could put themselves in because of the lack of knowledge and experience they have. The longer a person has the disease, the more they will forget. In the early stages of the disease a person may forget where they are or something somebody said to them, but in later stages of the disease, a person will forget their name or their relatives names. The child will be stuck with this disease for the rest of their life. The long-term outlook is that the child will need extensive care and supervision. Showing the child or adult pictures or home videos may help the person remember some memories, but not all. In rare cases, a patient with the disease will randomly become lucid. Becoming lucid means that you remember everything from before the disease, but not during the disease. If a patient becomes lucid, they should be taken to a hospital for a neurology exam.

Cause of the Disorder & Affected Genes

The cause of the disorder is a gene mutation to chromosomes APP, PSEN1, and PSEN2. Chromosomes 21, 14 and 1 are affected by Alzheimers. The disorder is autosomal dominant, which means one copy of the abnormal gene in each cell is sufficient to cause the disorder. In many cases, the affected person inherits the gene from one affected parent.

Interesting Facts

Alzheimers is characterized by the development of amyloid plaques and neurofibrillary tangles, the loss of connections between nerve cells in the brain, and the death of these nerve cells. There are two types of the disease; early onset and late onset. Alzheimers usually begins to affect a person around the age of 65 or later, this is known as late-onset. But, there are many cases around the world where teens and middle age adults have been affected by the disease.

Population Affected

Alzheimers is the most common in Western Europe, one in four people will develop the disease. In the United States, Nebraska has the leading Alzheimers patient history with 24.9 thousand people dying of the disease each year.
