The memory disturbances is often a sign of depression in older people. Unfortunately, none of us likes to admit we are having trouble with our memory, so people don t often complain about this, but it can often be caused by a depression that is treatable. Lets also talk about some of the diseases s that can cause depression in addition to their other signs and symptoms. Interestingly, anemia can look like an early onset of Alzheimer s if it is untreated and it can cause profound depression. Anemia can be ruled out very easily with a cbc or blood count.
Vitamin deficiencies can cause depression as well.
Vit B12 deficiency is particularly bad in terms of causing all kinds of memory problems and depression that can be mistaken for something else. Some diseases like Parkinson s can be associated with depression, as can stroke, and some neurologic tumors. Dehydration is also associated with depression. Disturbances in blood sugar can be associated with depression and other electrolyte imbalances. Infections can also be associated with depression.
