Genetic testing In some cases, genetic testing may be appropriate. Using this test early could indicate the likelihood of someone having or developing the disease.
However, the test is controversial, and the results are not entirely reliable. The death of brain cells cannot be reversed.
However, there are therapeutic interventions that can make it easier for people to live with the disease. Cholinesterase inhibitors that are approved for symptomatic relief in the U. Donepezil Aricept Rivastigmine Exelon Tacrine Cognex A different kind of drug, memantine Namendaan NMDA receptor antagonist, may also be usedalone or in combination with a cholinesterase inhibitor.
Other therapy The need for quality-of-life care becomes more important as the person becomes less able to live independently.
It is a neurodegenerative disease, which means there is progressive brain cell death that happens over time.
The plaques are found between the dying brain cells, and they are made from a protein known as beta-amyloid. The tangles occur within the nerve cells, and they are made from another protein, called tau.
Researchers do not fully understand why these changes occur. Several different factors are believed to be involved.
