Todd's paresis
Todd's Paresis
Todd's paresis (pronounced: /tɒdz pəˈriːsɪs/), also known as Todd's paralysis or postictal paresis, is a neurological condition characterized by a brief period of temporary paralysis or weakness in one or more limbs following a seizure.
Etymology
The term "Todd's paresis" is named after the Scottish physician Robert Bentley Todd (1809–1860), who first described the condition in 1849. The word "paresis" is derived from the Greek word "πάρεσις" meaning "letting go" or "paralysis".
Symptoms
The primary symptom of Todd's paresis is temporary paralysis or weakness in one or more limbs following a seizure. This can last from minutes to 36 hours. Other symptoms may include aphasia (difficulty with speech), ataxia (lack of muscle control), and hemianopsia (loss of half of the visual field).
Causes
Todd's paresis is typically caused by a seizure, specifically a focal seizure or a generalized seizure. The exact mechanism is not fully understood, but it is thought to be due to temporary changes in brain function following a seizure.
Diagnosis
Diagnosis of Todd's paresis is primarily based on the patient's medical history and physical examination. It is important to differentiate Todd's paresis from a stroke, as the symptoms can be similar.
Treatment
Treatment for Todd's paresis primarily involves treating the underlying cause, which is typically a seizure disorder. This may involve medications such as antiepileptic drugs.
