What are the symptoms of brain lesions?

Symptoms of brain lesions vary depending on the type of lesion, its extent, and where it is found. Everyone is different and symptoms will vary in individual cases. Many lesions, however, may be in areas of the brain that don’t produce symptoms.

Typical symptoms may include:

  • Headaches are usually the first symptom to appear with brain lesions. The pain appears suddenly and worsens as time passes. Over-the-counter medicine usually offers no relief for the pain.
  • Nausea and possible vomiting
  • Impaired movement, if the lesion affects the part of the brain responsible for motor skills
  • Lack of concentration, the inability to make quick decisions, and agitation
  • Delayed speech, blurred vision, and impaired hearing
  • Involuntary movements of body parts, which may progress to convulsions in severe cases

The following symptoms are specific to lesions of the frontal lobe:

  • Absence of sense of smell, usually limited to one nostril
