The basal ganglia tissue is an area in the brain with a blood supply that can be easily blocked or ends up damaged. If there is disruption in any region of the brain, the individual is at high risk for a stroke.
A stroke in the basal ganglia can trigger specific symptoms. By identifying these signs, the doctor can pinpoint the stroke and start the appropriate treatment.
Movement changes
A stroke that impairs the basal ganglia can result to various abnormalities in bodily movements. Rigid muscles, tremors and loss of movement are usual signs of a stroke in the basal ganglia.
It is important to note that the basal ganglia regulate the coordination of movement and once these nerve centers are damaged, there is loss of control which is called ataxia.
There is also weakness in the muscles used for swallowing as well as difficulty in talking and smiling. This is brought about by weakness in the muscles of the face, throat and mouth.
Cognitive impairment
Individuals who suffered from a stroke involving the basal ganglia might have diminished cognitive function. Some of the functions that are affected include memory, decision-making, attention and language. Even though these symptoms improve over time, they are rarely restored to normal levels.
Personality changes
A basal ganglia stroke can cause changes to the personality. Take note that there is a change in judgement. The individual might appear confused and has a hard time understanding what is occurring around him/her. In addition, the individual is easily anxious and frustrated, unmotivated and has lack of interest to previously enjoyed activities.
The individual also has inappropriate emotional responses where he/she might laugh or cry for no reason or end up with anger and depression.
What are the other signs?
If a hemorrhagic stroke involves the basal ganglia, it can trigger headaches, nausea and vomiting.
The bleeding within the caudate nucleus might even cover other parts of the brain. The blood can irritate the tissues and nerves of the brain and even result to discomfort and vomiting. In addition, the escalating pressure from the surplus blood can cause certain regions of the brain to shut down.
When the brain shuts down, the individual might lose consciousness and possibly enter a state of coma. Emergency evacuation of the excess blood and repair of the impaired blood vessels is the ideal treatment in such cases.
