Abstract: Enrichment of S and Z polymorphisms of alpha-1-antitrypsin (AAT) in distinct subsets of patients with cognitive disorder (pre-existing affective disorders and APOE2 allele carriers) suggests that AAT variants are potential endophenotypes for Alzheimer Disease and related disorders of cognition, behavior and affect. Such disorders include ADD/ADHD, learning disabilities, ADEM, and susceptibility to brain injury in toxic/chemical/biological/immunological events. In Alzheimer Disease, S and Z alleles affect age of onset and low AAT levels define faster progression rate. Twenty to thirty percent of all dementia patients display AAT and/or We polymorphisms. Effects of AAT may involve inflammation of liver/lung, macrophage activation and iron and lipid metabolism. AAT, its regulation, and iron metabolism represent therapeutic targets and AAT can serve as a biomarker for vulnerability and disease progression.

Abstract: The present invention relates, in general, to a method of preventing or delaying the onset of Alzheimer's disease and related neurodegenerative disorders. The invention also relates to a method of treating Alzheimer's disease and related neurodegenerative disorders so as to ameliorate the further progress of symptoms. The methods involve the administration of a non-steroidal anti-inflammatory agent and/or a histamine H2 receptor blocking agent. According to indication, the present method can be applied to individuals who are currently asymptomatic but at risk of developing Alzheimer's disease, to individuals who have mild cognitive symptoms that may either denote an incipient prodrome of Alzheimer's disease or represent early symptoms (prodromal stage), or to individuals who have a clinical diagnosis of Alzheimer's disease.

Abstract: The present invention relates, in general, to a method of preventing or delaying the onset of Alzheimer's disease and related neurodegenerative disorders. The method involves the administration to individuals at risk of developing the disease (or disorder) a non-steroidal anti-inflammatory agent and/or a histamine H2 receptor blocking agent. The invention also relates to a method of treating Alzheimer's disease and related neurodegenerative disorders that involves the use of such agents.
