"Abnormalities on imaging of the basal ganglia are often nonspecific. Therefore, a focused approach to limit the differential diagnosis is based on whether the patient presents with acute or chronic symptoms. The most sensitive sequence in the acute setting to detect abnormalities within the basal ganglia is diffusion-weighted imaging (DWI). The differential diagnostic considerations in the acute setting should include hypoglycemia, cerebral hypoxic encephalopathy, carbon monoxide poisoning, encephalitis, osmotic myelinolysis, toxin exposure, vascular causes, and illicit drug use."
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
