Alzheimer’s disease is a cruel disease that attacks individuals at a time
in their lives when life should be “good”. Alzheimer’s sinister advancement
in the human brain reduces a loving, caring grandma or grandpa into
a person who does not recognize the people they love the most.
The duration of Alzheimer’s disease may vary from as little as 3
years to 20 years. Memory and reasoning skills are usually the
first sign of the disease. But the disease will continue to
progress and other cells die in different regions of the brain.
The person who is in the latter stages of Alzheimer’s will need complete
care. The cruel results of this disease is that even though an
individual has no other serious illness, the loss of brain function
result in death.
Frontotemporal dementia differs from Alzheimer’s disease
in that the individuals retain their memory. The memory is
affected in these disorders but not to the level of those
patients who have Alzheimer’s disease. Patients who are diagnosed
with frontotemporal dementia retain their ability to carry out motor
For example: If a patient who has Frontotemporal dementia is a house painter
They may very well retain their ability to paint. The problem that is associated with
this dementia is primarily personality problems. However manual dexterity
remains in tact. The person with this disorder very seldom will get lost
or wander off as is the case with patients suffering from Alzheimer’s.
Dementia with Lewy Bodies
Dementia with Lewy bodies is the most commonly diagnosed form of progressive dementia. As in Alzheimer’s, there is a progressive decline in brain functioning. There are however additional features that are observed:
- Changes in alertness and attention
- Lethargy, such as frequent drowsiness
- Parkinson’s motor skill
The build-up of Lewy bodies which are bits of alpha-synuclein protein is considered the
cause of this disease. The accumulation of alpha-synuclein accumulation is also linked to Parkinson’s disease. There is a similarity between the symptoms of DLB ,Parkinson’s disease and Alzheimer’s disease. The similarities that exist between the different forms of dementia can make it difficult for a doctor to make a definitive diagnosis.
This disease is a rare degenerative disease that is always fatal. This disease affects about one person in every one million people worldwide. Symptoms usually start around the age of 60. Ninety percent of people who have this disease die within 1 year of diagnosis. Memory loss, behavioral changes, coordination and visual problems are early symptoms.
Parkinson disease is the most common form of degenerative dementia disease after Alzheimer’s. Parkinson’s is also a chronic, progressive disease that results when nerve cells in a part of the midbrain die or are impaired. These disturbances in the control centers of the brain cause the symptoms of PD.
Some of the same types of alpha-synuclein protein that is found in patients diagnosed with Lewy bodies are also found in the brains of people with Parkinson’s and Alzheimer’s diseases. These findings suggest to researchers and Doctors that either DLB is related to these other causes of dementia or that it is possible for an individual to have both diseases at the same time.
