The fear and anger instinctively would be very useful to protect yourself when someone is facing the threat. But this instinct can be lost due to the impact of the disease, either because they've had a stroke.
Stroke happens either because of a blockage or rupture of blood vessels in the brain are known to cause damage to brain cells. Decreased oxygen supply during the stroke to make some cells in the brain tissue damage or even death.
If damage occurred to the front of the brain, then some brain function will be impaired, especially related to the emotions. It functions lai instinct to feel fear, anger and other emotions forms that usually appears when there is a threat.

A study will be presented at the American Stroke Association to prove it through observation of 23 young stroke patients. The patients had a stroke at the basal ganglia, which is one part of the forebrain.
The observation of the behavior and also scanning with functional magnetic resonance imaging (fMRI) showed that part of the brain that regulates emotion experienced a decline in activity. Quoted from HealthDay, this difference is very significant when compared with 68 healthy adults.
The researchers suggest, stroke patients who suffered damage to the front of the brain should be given extra treatment during the recovery period. Interest psychological and behavioral therapy is to restore the ability to recognize fear making it more sensitive to the threat of danger.
Instinctively, fear and anger are useful to protect a person from harm's way. When dealing with hazardous conditions, fear of encouraging someone to avoid, while anger will drive the courage to fight.
Details of the research to date has not been provided, as will be examined at a scientific meeting that will take place in New Orleans next week.
