AD is a progressive disease that destroys memory and other important mental functions. Brain cell connections and the cells themselves degenerate and die, eventually destroying memory and other important mental functions. Memory loss and confusion are the main symptoms. No cure exists, but medications and management strategies may temporarily improve symptoms.

Familial Alzheimer's Disease is caused by any one of a number of different single-gene mutations on chromosomes 21, 14, & 1 for early onset and chromosome 19 for late onset. Each of these mutations causes abnormal proteins to be formed.

Correct Mechanism-
The G-Protein receptor waits for a ligand to connect and activate to it, which causes the signal to be amplified through the cell to the target to create a molecular reaction for the cell.
Incorrect Mechanism-
The G-Protein and the receptors all work perfectly fine. However, neurotransmitters deteriorate before they can reach the G-Protein to activate the rest of the cell processes. Many of these reasons are unknown and being researched as we speak.

Researchers are working to uncover as many aspects of Alzheimer's disease and other dementia as possible. Some of the most remarkable progress has shed light on how Alzheimer's affects the brain. The hope is this better understanding will lead to new treatments. Many potential approaches are currently under investigation worldwide.
