From the Guidelines
Todd Syndrome, also known as Todd's paralysis, is a neurological condition characterized by a temporary weakness or paralysis of a part of the body following a seizure, which can be mistaken for a stroke. This condition is often seen in patients who have experienced a seizure, particularly those with a history of epilepsy [ 1 ]. The symptoms of Todd Syndrome can be similar to those of a stroke, making it challenging to differentiate between the two conditions based on clinical examination and brain CT scan alone.
Key Characteristics
- Temporary weakness or paralysis of a part of the body
- Often occurs after a seizure
- Can be mistaken for a stroke
- Symptoms typically resolve within 24-48 hours
Diagnosis and Management
Diagnosing Todd Syndrome can be difficult, as it requires distinguishing it from other conditions such as stroke. Advanced imaging techniques like magnetic resonance diffusion and perfusion-weighted images, angiography, perfusion CT, or CT angiography can be helpful in making an accurate diagnosis [ 1 ]. Management of Todd Syndrome focuses on treating the underlying cause of the seizure and providing supportive care to manage symptoms.
Important Considerations
- Todd Syndrome is a temporary condition, and symptoms usually resolve on their own within a short period
- It is essential to differentiate Todd Syndrome from stroke, as the treatment approaches for these conditions are different
- Advanced imaging techniques can be useful in making an accurate diagnosis and guiding management [ 1 ]
From the Research
Definition and Characteristics of Todd Syndrome
- Todd syndrome, also known as Todd's paralysis, is a neurological abnormality characterized by temporary limb weakness or hemiplegia, typically occurring following a seizure, without enduring consequences 2.
- The condition is often difficult to diagnose in individuals experiencing an acute ischemic stroke if they do not have a pre-existing history of epilepsy.
Clinical Manifestations and Diagnosis
- Todd's paralysis is commonly observed after partial seizures or generalized tonic-clonic seizures 2.
- The incidence of Todd's paralysis is greater if the epilepsy is associated with old age or stroke history 2.
- The duration of Todd's paralysis can range from minutes to days, depending on the type of seizure or whether the patient has experienced cortical structural damage 2.
- The etiology of Todd's paralysis is associated with cerebral perfusion abnormality after seizures 2.
Distinction from Other Conditions
- Factors that may help clinicians distinguish Todd's paralysis from other clinical indications include the type of seizure, patient's age, and history of stroke 2.
- Further research is needed to explore factors that distinguish Todd's paralysis from other indications that may lead to limb weakness in order to improve the diagnosis of Todd's paralysis 2.
