A body of evidence exists discussing a positive secondary effect of antidepressant use. Hippocampus cell growth is the result which comes as a byproduct. The hippocampus is a structure within the brain which stores memories systematically. Typically examined in those with long term depression, studies show that with use of antidepressants over extended periods of time, hippocampus cells proliferate and increase in plasticity. If the hippocampus cells are generating, or even if the plasticity is allowing new information to be stored and retrieved, then implications could be profound.
The use of antidepressants can be very beneficial for the elderly and those with dementia, for decreasing depression, but perhaps there is an additional benefit. Wouldn’t it be amazing if we could kills two birds with one stone, or at least slow down the migrating flight of memory loss throughout the fragile brains of those with dementia, Alzheimer’s, or normal age related memory impairment.
Now I have to say that doctors do not prescribe antidepressants for this purpose, and research is virtually nonexistent in hippocampus volume increase with the population whose diagnosis is that of a memory disease such as Alzheimer’s. What’s available is the promise of clinical trials related to this concept. Here is a link to one such trial, and this site will provide a tool to find other trials as well that may benefit our patients and loved ones with dementia.

More than a clinical trial, the promise or hope that perhaps a treatment we use for one symptom, depression, will change the brain with memory loss in a positive way may provide solace in the face of a very challenging disease.
