A health expert has introduced a simple 30-second test that could help detect hidden brain issues—using nothing more than your hands.

This quick, at-home screening method is gaining attention for its potential to reveal early signs of neurological problems, including stroke risk, nerve dysfunction, or degenerative brain conditions like Parkinson’s disease.

The Test: What to Do

1. Stretch your arms straight out in front of you with palms facing up.

2. Close your eyes and hold this position for 30 seconds.

3. Watch (or have someone else observe) for any of these signs:

   • One hand starts to drift downward

   • The palm begins to rotate inward

   • The arm begins to tremble or weaken

What It Might Mean

• Arm drift or weakness: Could indicate a transient ischemic attack (TIA) or minor stroke.

• Tremors or rotation: May be a subtle sign of early Parkinson’s disease.

• Incoordination: Might point to neurological issues affecting motor control.

While the test isn’t a diagnosis, it can be a red flag signaling the need for a professional medical evaluation.

Why Early Detection Matters

Many brain-related conditions develop silently, with few or no symptoms in the early stages. Catching them early improves treatment outcomes and can even prevent severe complications.
