Lacunar stroke

A lacunar stroke is a form of ischemic stroke that occurs if the flow of blood to one of the small arteries deep inside the brain is clogged.

What are the signs?

The indications of a stroke typically arise abruptly and without any warning. The usual signs of a lacunar stroke include:

  • Inability to raise one arm
  • Slurred speech
  • Difficulty walking or moving the arms
  • Numbness, usually on only one side of the body

    The indications of a stroke typically arise abruptly and without any warning.

  • Drooping on one side of the face
  • Headache
  • Memory issues
  • Confusion
  • Difficulty speaking or understanding
  • Loss of consciousness or coma

Once the brain cells die, the functions regulated by that side of the brain are affected. These signs tend to vary depending on the site of the stroke.

Management of a lacunar stroke

If an individual develops a lacunar stroke, prompt treatment improves the chances of survival and prevent further damage. Upon arrival at the emergency department, aspirin and other drugs are given to lower the risk for another stroke.

Supportive care might be necessary to help with the heart function and breathing. Intravenous clot-busting drugs are given as well. In severe cases, the doctor might provide drugs directly into the brain.

A lacunar stroke can result to some degree of brain damage. The recovery tends to vary for every individual and seriousness of the stroke.

What is the outlook?

The quality of life of the individual after a lacunar stroke is based on various factors including the age and how treatment was started after the symptoms arise. In some cases, the disabilities are permanent such as:

  • Numbness
  • Paralysis
  • Tingling sensation in the affected limb
  • Loss of muscular control on one side of the body

Even after rehabilitation and recovery from a stroke, there are issues with short-term memory while some have difficulty with reasoning and thinking.
