There are two main classification systems for BGH:

Anatomical Classification: Based on the location of the hemorrhage within the basal ganglia, it can be classified into the following types:

[[Putaminal Hemorrhage]]

[[Caudate Hemorrhage]]: This type of BGH occurs in the [[caudate nucleus]], which is located in the center of the basal ganglia. Caudate hemorrhage can cause a range of symptoms, depending on the location and size of the hemorrhage, but commonly causes contralateral hemiplegia and cognitive impairment.

Globus Pallidus Hemorrhage: This type of BGH occurs in the globus pallidus, which is located below the putamen. Globus pallidus hemorrhage can cause a range of symptoms, including hemiparesis, hemisensory loss, and abnormal eye movements.

Clinical Classification: Based on the severity and extent of bleeding, BGH can be classified into the following types:
Small BGH: In this type of BGH, bleeding is limited to a small area of the basal ganglia and typically causes mild symptoms.

Moderate BGH: In this type of BGH, bleeding is more extensive and may involve multiple areas of the basal ganglia. Symptoms are usually more severe than in small BGH.

Large BGH: In this type of BGH, bleeding is extensive and involves a significant portion of the basal ganglia. Large BGH typically causes severe symptoms and can be life-threatening.
