A stroke is a serious medical condition that the National Institutes of Health (NIH) defines as "an interruption of the blood supply to any part of the brain." Two types of strokes can occur: an ischemic stroke, caused by a blood clot, or a hemorrhagic stroke, caused by a ruptured blood vessel. Each type can cause long-term damage to the brain, including problems with cognitive function, emotions and personality.
Cognitive Function Changes
The Stroke Recovery Association says that after a stroke, the patient can have problems with memory and thinking. The severity of these problems depends on the extent of the brain damage. Examples of memory problems are difficulty remembering daily events or schedule, and issues recalling names and faces. Thinking problems can include difficulty following directions. The American Stroke Association adds that the patient may also have issues solving problems.
Emotional Changes
Emotional changes can occur after a stroke, such as the patient falling into a deep depression. The American Stroke Association quotes Dr. Janet Spradlin as saying "depression is very common after any life-changing health challenge, especially if it means a loss of independence." The Stroke Recovery Association notes that the patient may also have emotional liability, in which the patient cannot control her emotions. This can appear strange to onlookers, as the patient may cry during a happy occasion or laugh during inappropriate times.
Personality Changes
The Stroke Recovery Association says that changes in personality after a stroke are rare but can be disturbing to the patient's loved ones. The patient may appear more irritable, confused, self-centered or uncooperative. Rapid mood changes can also occur. The American Stroke Association adds that the patient may also become apathetic, where it appears that he doesn't care about things going on around him.
