Basal Ganglia Stroke – Symptoms, Prognosis, Recovery, Treatment

Basal Ganglia Stroke – Symptoms, Prognosis, Recovery, Treatment

What exactly is a Basal Ganglia Stroke?


The tissue of the basal ganglia is made up of the putamen, globus pallidus and caudate nucleus and is a region in the brain. This region has a supply of blood that easily can suffer damage or be blocked. When the supply of blood to any region in the brain is disturbed, the individual will undergo a stroke. When a stroke occurs because of lack of blood flow in the basal ganglia, it leads to symptoms which are very explicit. It is by detecting these indicators that a medical professional can pinpoint the stroke area and then deliver the appropriate treatment.








Basal Ganglia Stroke Symptoms


The typical symptoms for a stroke in this area include:


Changes in body movement – strokes in this area can create a variety of anomalies in movement of the body. These include:



  • Rigid, stiff muscles

  • Movement loss

  • Tremors

  • Ataxia

  • Difficulty swallowing

  • Difficulty in smiling or speaking


Cognitive impairment – some individuals will experience reduction in cognitive functioning, such as:



  • Ability to make decisions

  • Memory

  • Language

  • Attention


Unconsciousness, nausea, vomiting and headache – when bleeding occurs in the basal ganglia region can migrate to other regions of the brain. This bleeding irritates the tissues and nerves and can lead to vomiting and pain. Any pressure increase can lead to areas of the brain shutting down.


Personality changes – The following symptoms can occur:



  • Difficulty understanding

  • Frustration

  • Anxious

  • Lack of motivation

  • Loss of interest in any activities

  • Crying for no reason

  • Laugh for no reason

  • Depression

  • Anger


Basal Ganglia Stroke Recovery


Most individual start the recovery process from a stroke virtually moments after the stroke happening. Recovery which is spontaneous usually explains the majority of progress in the first month after a stroke. Any recovery that is positive hinges on:

  • Brain damage extent

  • Individual’s attitude

  • Skills of the medical professionals

  • Assistance of friends and family.


But not every patient recovers on their own. For these individuals, rehabilitation therapy can be irreplaceable. Successful rehabilitation depends on:

  • Learning new skills to replace old ones that have been lost

  • Areas of the brain taught to take over work of the damaged areas

  • Rehabilitation begins as quickly as possible


Basal Ganglia Stroke Prognosis


Exactly how well a person will progress from this type of stroke depends on several factors – such as:



  • Severity of any impairment

  • Exact location of injury to the brain

  • Individual’s age

  • Individual’s general medical condition


Many dysfunctions are reversible while others may require lifelong treatment


Basal Ganglia Stroke Treatment


Any symptoms of a stroke needs to immediately be worked up in a hospital. The diagnosis of a stroke is based on the individual’s history, a neurological exam as well as brain imaging. A CT scan can show fresh blood in the skull.


During the acute phase of a stroke, patients need to be kept under close observation and might even require support in an intensive care unit. Treatment at this stage can range from conservative treatment consisting of:



  • Pain medication

  • Stabilizing vital signs

  • Lowering pressure inside the head


To invasive treatment options which consist of:



  • Surgery to removing any blood to relieve pressure

  • A shunt operation to drain the system


The largest acute complication is more bleeding from the original source. Approximately 20% of patients will have a further incident of bleeding during this time.


After the acute phase it is important to start early rehabilitation. Rehabilitation therapy is vital to getting the patient back to health as quickly as possible. Successful rehabilitation depends on:



  • Learning any new skills in order to replace old ones that were lost

  • Teaching areas of the brain to take over the work of any damaged areas

  • Skilled medical team

  • Support team involving medical professionals as well as family and friends
