Sudden changes in speech, balance, and coordination can signal an urgent health concern, especially when they fade quickly or recur.

Migraine can’t be diagnosed using a blood test, imaging scan, or biopsy. Rather, doctors typically diagnose this headache disorder solely through a person’s reported symptoms (including how often they occur and how long they last), triggers, and a family history of migraine.

When clonazepam doesn’t ease the unsteadiness of orthostatic tremor, other medicines may offer options to discuss with your doctor.

Suspected thoracic outlet syndrome can resemble other conditions, so careful evaluation helps determine which specialist and treatment are appropriate.

A 2026 study found that older “super-movers”—adults 80 and older who walk significantly faster than their peers—were substantially less likely than slower walkers to develop cognitive impairment and had larger memory-related brain regions, suggesting that brisk walking speed may signal, or even support, healthier brain aging.
