Research is still needed in the area of cerebellar stroke management; however, several factors may lead to poor outcomes in individuals who have a cerebellar stroke. These factors include: Declining levels of consciousness; New signs of brainstem involvement; Progressing Hydrocephalus; Stroke to the midline of the cerebellum (a.k.a. the vermis) [4]
The lack of blood flow results in cell death and subsequent breakdown of the blood vessel walls, leading to bleeding. While this bleeding can result in further injury, it is itself a marker for injury that has already occurred. Most intraventricular hemorrhages occur in the first 72 hours after birth. [9]
Holmes tremor, first identified by Gordon Holmes in 1904, can be described as a wing-beating movement localized in the upper body that is caused by cerebellar damage. [1] Holmes tremor is a combination of rest, action, and postural tremors.
This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. [2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage. [3] Ischemia leads to alterations in brain metabolism, reduction in metabolic rates, and energy crisis.

Cerebellar degeneration is a condition in which cerebellar cells, otherwise known as neurons, become damaged and progressively weaken in the cerebellum. [1] There are two types of cerebellar degeneration; paraneoplastic cerebellar degeneration , and alcoholic or nutritional cerebellar degeneration. [ 2 ]
The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis . [ 5 ]
Posterior circulation infarct (POCI) is a type of cerebral infarction affecting the posterior circulation supplying one side of the brain.. Posterior circulation stroke syndrome (POCS) refers to the symptoms of a patient who clinically appears to have had a posterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the diagnosis.
Presumed perinatal stroke is a condition when the stroke is only diagnosed after the neonatal period and does not have any significance in neurological examination within the 28 days after birth. [19] The majority of infants who were later diagnosed with presumed perinatal stroke were free of symptoms during the neonatal period. [20]
