The same molecule that is involved in cell-to-cell recognition in the immune system also seems to play a major role in the brain’s developmental wiring process. In animals, this molecule is called the commonly cited as MHC,a cluster of genes located on chromosome 6 concerned with antigen production and critical to the success of transplantation. The MHC includes the human leukocyte antigen (HLA) genes.
Alexithymia means “no words for feelings.” It is a state predominantly seen in males. People exhibiting alexithymia have a difficult time speaking about, or even being aware, of their feelings. Interestingly, researchers have found that alexithymia and engineer’s syndrome is often seen in people with hair loss, skin diseases, anxiety and depression. (See the skin and hair sections below).

The insula, a structure found between the temporal lobe and the frontal lobe, is related to olfactory, gustatory, visceral, and limbic function. The posterior insula is related to auditory sensation, bodily sensations, and skeletomotor function. It also plays an important role in the experience of pain and mediates emotions, including disgust, anger, fear, empathy, happiness, and sadness. A stroke in this part of the brain can present with the attenuation or loss of these abilities, and often presents as a mental disorder. Interestingly, smokers who have a stroke in the insula stop smoking immediately.

The basilar artery is the large artery coming up through the spinal cord into the bottom of the brain. Symptoms of a basilar artery stroke are avolition, apathy, and dizziness. A common but unusual symptom is pathologic laughing or crying.
Let me know about good onlinesources in addition to these:
A is an event that is not seen as a stroke. There is no paralysis or other motor problems. Strokes of this nature are sometimes misdiagnosed as a mental illness.

are strokes that last only a few minutes. For this reason, they generally do not cause permanent damage, but they are a critical warning. About 10 percent of strokes are preceded by TIAs. Researchers in the ongoing Northern Manhattan Stroke Study have shown an association between periodontal disease, a chronic low grade infection of the bone underlying the teeth and a thickening of carotid artery plaque, and a major risk of stroke.

Researchers from the National Institute on Aging in Bethesda Maryland have found a significant increase in brain tumors in people over the age of 75. The incidence of the tumors has doubled from 1968 to 1985 (which was the last year for which statistics were available). For those over 80, the rate of increase was 300 percent, which is an increase of 23 percent per year.
