Progressive supranuclear palsy (PSP) can stem from cerebrovascular disease, not just idiopathic causes. Vascular PSP often presents with asymmetric, lower-body symptoms, distinguishing it from the idiopathic form.

Area of Science:

Neurology
Neuroscience
Vascular Neurology

Background:

Progressive supranuclear palsy (PSP) is a rare neurodegenerative disorder of unknown etiology.
Idiopathic PSP typically presents with specific clinical and pathological characteristics.
Investigating potential causes beyond idiopathic origins is crucial for understanding PSP.

Observation:

This study reviewed 128 patients diagnosed with PSP to identify evidence of cerebrovascular disease.
A subset of patients (23.3%) met criteria for vascular PSP.
Clinical and neuroimaging features were compared between vascular and idiopathic PSP groups.

Findings:

Vascular PSP was associated with asymmetric and predominantly lower-body involvement (p < 0.05).
While corticospinal and pseudobulbar signs, gait issues, dementia, and incontinence were more frequent in the vascular group, these did not reach statistical significance.

The findings suggest cerebrovascular disease as a potential cause of PSP.

Implications:

Cerebrovascular disease should be considered in the differential diagnosis of PSP.
Vascular PSP may be distinguished by greater asymmetry, lower body symptoms, and specific neurological signs.
Identifying vascular causes could lead to targeted treatments and improved patient outcomes.
