Basal ganglia stroke: What are the indications?

The basal ganglia tissue is an area in the brain with a blood supply that can be easily blocked or end up damaged. In case the blood supply to any region of the brain is disrupted, the individual ends up with a stroke. A basal ganglia stroke triggers specific symptoms.

Movement changes

A basal ganglia stroke can cause abnormalities in the body movement such as the following:

  • Stiff muscles
  • Tremors
  • Loss of movement

    There is weakness in the muscles used in swallowing and difficulty in talking and smiling is evident.

The basal ganglia controls coordination of movement and once these nerves centers are impaired, the body loses this ability which is called ataxia.

There is weakness in the muscles used in swallowing and difficulty in talking and smiling is evident. This is brought about by the weakening in the muscles in the mouth, face and throat. The nerves in the basal ganglia are responsible for innervating these muscles. If it is damaged due to a stroke, these muscles weaken and function erratically.

Cognitive impairment

Individuals will experience diminished cognitive functioning. Some of the functions affected by basal ganglia stroke include memory, decision-making ability, attention and language. Any issues recover over time but rarely return to their usual levels.

Changes in personality

A basal ganglia stroke can result to personality changes such as the following:

  • In most cases, there is a change in judgment.
  • The individual also appears confused and has difficulty understanding what is happening around.
  • Individual appears frustrated and anxious.
  • Loss of motivation and shows lack of interest in activities that were previously important.
  • Inappropriate emotional responses
  • Individual might laugh or cry without apparent reason
  • Episodes of anger and depression

What are the other indications?

If a hemorrhagic stroke occurs, it can trigger symptoms such as:

The bleeding in the caudate nucleus tends to spread to other parts of the brain. This blood irritates the tissues and nerves of the brain and trigger pain and vomiting. In addition, the increased pressure due to the excess blood can cause the shutdown of parts of the brain.

When the brain starts to shut down, the individual loses consciousness and possibly enter a state of coma. In such cases, emergency evacuation of the excess blood and repair of the damaged blood vessels is required.
