Indications of basal ganglia stroke

A basal ganglia stroke is known to cause specific symptoms. The basal ganglia tissue is comprised of the caudate nucleus, globus pallidus and putamen. This region of the brain has a supply of blood that can be easily clogged or endure damage. In case the blood supply to any part of the brain is disrupted, the individual suffers a stroke. Being able to identify the symptoms of a basal ganglia stroke is vital so that the doctor can pinpoint the condition and provide the right treatment.

Movement changes

Strokes that impair the basal ganglia can lead to irregularities with body movement. Rigid muscles, tremors and loss of movement are possible symptoms of a basal ganglia stroke.

The basal ganglia are responsible for controlling the coordination of movement. Once these nerve centers are damaged, the body will lose this ability which is a condition known as ataxia.

Rigid muscles, tremors and loss of movement are possible symptoms of a basal ganglia stroke.

The individual can also complain of muscular weakness which is required for swallowing and difficulty smiling and talking. Take note that this is due the weakness in the muscles of the mouth, face and throat. The nerves in the basal ganglia are responsible for these muscles. Once they are damaged by stroke, these muscles eventually weaken and poorly function.

Cognitive impairment

Those who have experienced a stroke that affects the basal ganglia usually suffer diminished cognitive function. Some of the functions that are affected by basal ganglia stroke include the following:

  • Language
  • Decision-making ability
  • Memory
  • Attention

Always bear in mind that these symptoms eventually improve over time but rarely return to normal levels.

Personality changes

A basal ganglia stroke can cause changes to the personality. In most circumstances, an individual will appear confused and have a hard time understanding what is happening around them.

The individual can also become easily anxious or frustrated. Some lack motivation and show inappropriate emotional responses. In addition, the individual can laugh or cry for no evident reason or suffer from anger and depression.

What are the other symptoms?

If the individual had a hemorrhagic stroke in the basal ganglia, it can result to headache, nausea and vomiting. Bleeding in the caudate nucleus can radiate to other parts of the brain. Take note that the blood can irritate the tissues and nerves of the brain and result to pain and vomiting.

The increasing pressure due to the accumulation of excess blood can lead to the shutdown of certain parts of the brain. Once the brain starts to shut down, the individual loses consciousness and progresses to a state of coma. Immediate drainage of the excess blood and repair of the damaged blood vessels is the ideal treatment in such cases.
