Why does depression make you lose your memory?
Declarative memory, which
involves the retention of facts and events, may be less effective when a person
is depressed. The hippocampus,
a stress-sensitive region of the brain involved in learning and memory, is
often smaller in depressed individuals. Low hippocampus volume may be the cause
of poor memory.
These results provide credence to
the hypothesis that melancholy may impair declarative memory, which involves
remembering facts and experiences. The study's authors postulate that
depression might inhibit the growth of new nerve cells. This can make it
challenging to create or access fresh memories.
Acute and long-term alterations brought on by stress can harm some parts of the brain. The most common memory impairment caused by excessive stress hormone production is long-term delayed recall memory, although it can also improve short-term, instant recall memory. This improvement is most noticeable in emotional memory.
