Hello again —
Today I’ll continue on with some of the other types of Alzheimer’s dementia. Then, in the next article, I’ll get into a discussion of what is know about the causes of Alzheimer’s and some of the history, as well. I’ll also keep interspersing my articles with other topics so that those of you that don’t want, or need, to know about this topic won’t get too bored.
A significant number of people diagnosed with dementia are found to have tiny spherical structures called Lewy bodies in the nerve cells of their brains. It is thought these may contribute to the death of brain cells.
The symptoms of this form of dementia are often mild at the outset and can be extremely variable from day to day. Common symptoms include :
Ø Fluctuation in the condition
Ø Visual hallucinations
Ø Extreme sensitivity to classical anti-psychotic medications leading to marked symptoms of stiffness, tremor and restriction of movement
Dementia with Lewy bodies sometimes occurs with Alzheimer’s disease and Vascular dementia.
Pick’s Disease causes progressive and irreversible decline in a person’s abilities over a number of years. It is a rare disorder of the frontal part of the brain which can be very difficult to diagnose. The disease usually appears between 40 and 65 years of age.
Disturbances of personality, behavior and language may come before, and initially be more severe than, memory defects.
Huntington’s Disease is an inherited degenerative brain disorder which affects the mind and body.
Huntington’s Disease affects approximately 7 in every 100,000 people in the western world. The disease usually appears between 30 and 50 years of age.
Huntington’s Disease is characterized by intellectual decline and irregular, involuntary movement of the limbs or facial muscles. Other symptoms include:
Ø Personality change
Ø Memory disturbance
Ø Slurred speech
Ø Impaired judgment
Ø Psychiatric problems
There is no treatment available to stop the progression of this disease, but medication can control movement disorders and psychiatric symptoms.
Dementia occurs in the majority of Huntington’s Disease cases.
Too much alcohol, particularly if associated with a diet deficient in thiamine (Vitamin B1) can lead to irreversible brain damage. This dementia is preventable.
If people don’t drink, or they drink at a safe level, then they cannot develop Alcohol Related Dementia. The most vulnerable parts of the brain are those used for memory, and for planning, organizing and judgment, social skills and balance. If drinking stops there may be some improvement. Taking thiamine appears to help prevent and improve the condition.
Creutzfeldt-Jacob Disease is also known as Mad Cow Disease.
An extremely rare and fatal brain disorder caused by a prion, which is a protein particle. The disease occurs in one in every million people per year.
The early symptoms of this disease include:
Ø Failing memory
Ø Changes in behavior
Ø Lack of coordination
After which, the disease progresses rapidly, resulting in :
Ø Pronounced mental deterioration
Ø Involuntary movements appear
Ø Person may become blind
Ø Develop weakness in the arms or legs and finally lapse into a coma
This disease can jump species barriers, and can affect cows, humans, and other animals.
The Australian Red Cross (and other Red Cross organizations around the world) expressly forbid anyone who lived in the United Kingdom between the years of 1980 and 1998 to donate blood, because of the higher than average possibility that they consumed beef from slaughtered Mad Cows that entered the human food chain in the UK (in spite of promises and guarantees from numerous UK politicians). It is feared that these people will go on to develop Mad Cow Disease later in life, and if they were allowed to donate blood, that the recipients of this blood could also develop the disease.
The term Mild Cognitive Impairment, or MCI, is increasingly being used to describe a syndrome of memory impairment that does NOT significantly impact daily activities and is not accompanied by declines in overall cognitive function.
Researchers have found that between 6 and 25 percent of people with MCI progress on to Alzheimer’s, which has raised questions about whether MCI might represent some kind of "transitional stage" between normal aging and dementia.
Many experts currently believe that MCI, as well as age-related memory loss, may be an early form of Alzheimer’s, and progression to symptomatic Alzheimer’s disease may be only a matter of time.
However, in some people, the progression may be very slow, so the person may die of other causes before displaying the full spectrum of Alzheimer’s symptoms.
MCI is recognized as a clinical condition that requires ongoing assessment and possibly treatment to delay its progression.
Research into MCI is continuing.
Thanks for reading. We’ll be back with more in a couple of days.
