“. . helping to support the survival of existing neurons, and encourage the growth and differentiation of new neurons and synapses.”
“It is also expressed in the retina, motor neurons, the kidneys, saliva, and the prostate.”
“BDNF itself is important for long-term memory.”
“Various studies have shown possible links between BDNF and conditions, such as depression,[63][64] schizophrenia,[65] obsessive-compulsive disorder,[66] Alzheimer's disease,[67] Huntington's disease,[68] Rett syndrome,[69] and dementia,[70] as well as anorexia nervosa[71] and bulimia nervosa.[72]- Note: Most of these conditions are strongly also associated with low vitamin D

“Expression of this gene is reduced in Alzheimer's, Parkinson's, and Huntington's disease patients.”
