A person who has had a stroke may laugh or cry inappropriately or for no clear reason. This loss of emotional control can be confusing or upsetting to the patient, as well as to family or friends. This is a result of the stroke and usually does not last a long period of time. The person may also show signs of fear, hostility, frustration, and anger, which may lead to withdrawal and isolation. Much support is needed from family and friends, as he or she may at times feel like the situation is hopeless.
