ABOUT DEMENTIA
Dementia is an overachieving term that covers a vast range of medical conditions including Alzheimer’s disease (which is the most commonly known form). Disorders like Dementia are usually caused by unusual changes in the brain.
The most prevalent form of Dementia is Alzheimer’s disease accounts for 60 to 80 percent of cases. The second most common type is Vascular Dementia which involves bleeding and blood vessel blockage in the brain. Research also indicates that Dementia with Levy Bodies could be the second most prevalent form of Dementia which involves abnormal deposits of a protein called alpha-synuclein in the brain. Other conditions that can cause symptoms of dementia include thyroid problems and vitamin deficiencies, but these are reversible.
Many times, Dementia is incorrectly labelled as “senility” or “senile dementia” which incorrectly messages that serious mental degradation is a normal part of aging.
EFFECTS ON THE BRAIN
All throughout the brain, there is nerve cell death and tissue loss. Eventually, as time passes, the brain gets smaller and its functions are affected.
A CLOSER LOOK
After a lot of research scientists are still not sure exactly what causes cell death and tissue loss; however, they have found probable causes. Looking at the brain, they found that plaques and tangles which are shown below are most likely the causes. Alzheimer's tissue has fewer nerve cells and synapses than a healthy brain.
