A lacunar stroke is a type of ischemic stroke caused by blockage of a small blood vessel deep within the brain. It can produce relatively subtle symptoms, which is one reason it may be mistaken for “just getting older.”
7 signs that shouldn’t be overlooked
- Sudden weakness on one side
One arm, leg, or side of the face may suddenly feel weak or clumsy.
- Sudden numbness or altered sensation
Numbness or unusual sensation affecting one side of the body can occur.
- A suddenly clumsy hand
Difficulty buttoning a shirt, holding a cup, writing, or performing precise movements—particularly when it appears suddenly—can be a warning sign. Dysarthria–clumsy hand syndrome is one recognized lacunar presentation.
- Suddenly slurred speech
Speech may become thick, slow, or difficult to understand even when the person knows what they want to say. This can occur without the dramatic symptoms people commonly associate with stroke.
- Sudden trouble walking or coordinating movements
A person may suddenly become unsteady, have difficulty walking, or develop weakness combined with poor coordination.
- Sudden weakness and numbness together
A combination of sensory and motor symptoms on one side can occur with a lacunar stroke.
- Symptoms that briefly disappear
Don’t assume a problem is harmless because it went away. A TIA can cause temporary stroke-like symptoms and requires urgent assessment because it can precede a major stroke.
🚨 Especially important
These aren’t symptoms to watch at home. A sudden neurological change is a medical emergency. Use B.E. F.A.S.T.: Balance problems, Eye/vision changes, Face drooping, Arm weakness, Speech difficulty, and Time to call emergency services. Note when the symptoms started, even if they subsequently improve.
Also, being over 60 doesn’t make sudden weakness, clumsiness, or speech changes a normal part of aging. Don’t drive yourself to the hospital; call emergency medical services.
