Eye shaking, or nystagmus, is usually caused by an underlying neurological issue.
Types and Causes of Eye Shaking
There are two main types of nystagmus:
- Congenital Nystagmus: This type is present from birth or develops early in childhood. The exact cause is often unknown, but it's linked to neurological problems.
- Acquired Nystagmus: This type develops later in life and can be a symptom of another condition or disease. Examples include:
- Stroke: Damage to the brain from a stroke can disrupt the neural pathways controlling eye movement.
- Multiple Sclerosis (MS): This autoimmune disease can affect the nerves that control eye movement.
- Trauma: Head injuries can damage the brain structures responsible for eye coordination.
- Other Neurological Conditions: Various other neurological conditions can contribute to acquired nystagmus.
The reference states that nystagmus is "most commonly caused by a neurological problem that is present at birth or develops in early childhood." Acquired nystagmus, occurring later in life, signifies another underlying condition like stroke, multiple sclerosis, or trauma.
Understanding the Neurological Connection
Eye movement is a complex process controlled by several areas in the brain. Disruptions to these areas, whether congenital or acquired, can lead to involuntary eye shaking. The exact mechanism varies depending on the underlying cause.
