Alzheimer's disease has features in common with both Parkinson's and Huntington's diseases. kindred Parkinson's disease, Alzheimer's involves alteration in brain biochemistry; specifically it is associated with acquittance of neurotransmitters within the cerebral cortex. In addition, as with Huntington's disease, the disorder whitethorn also be inherited.

e child. The information processed in her left hemisphere was evidenced by her left brain language response.

What treatments are useful in treating degenerative disease?

Another degenerative brain disease, Huntington's disease, was first described by George Huntington. Dr. Huntington's analyses of the disorder were based on cases that he himself, his father, and his grandfather in the first place him had observed in their practices. The condition generally develops in patients in their late 30's and early 40's. It is an inherited disorder passed from one contemporaries to the next according to autosomal dominant transmission.
