Brain-Derived Neurotrophic Factor, Copper, Zinc and High Density Lipoprotein (HDL) in Patients with Dementia

The levels of BDNF, copper, zinc and common blood tests of two different groups of patients were considered: those with dementia syndrome and healthy older people. It would be premature to conclude that these indicators, with the exception of high density lipoprotein (HDL), are directly associated with clinical manifestations of this disorder. The HDL levels were significantly lower in dementia patients, compared to healthy control group, so it is possible to suggest that HDL can perform a protective function.
