The G allele is associated with higher enzymatic activity and more rapid drug metabolism. Most of autosomal dominant familial AD can be attributed to mutations in one of three genes: Inflammation is a general marker of tissue damage in any disease, and may be either secondary to tissue damage in AD or a marker of an immunological response. In affected members of 2 families with AD1, Goate et al. Migraine Familial hemiplegic Cluster Tension.

Neurons of Alzheimer patients show a neurofibrillary tangle that is made up of disordered microtubules. However, amyloid deposits build up in the brain, leading to further deterioration.

Higher than normal levels of calcium in the brain cells causes damage to them and also prevents them from receiving signals from other brain cells.
