Summary
Poststroke seizures are common in adults after stroke. Differentiating early and late seizures guides treatment, with late seizures often requiring long-term medication.
Area of Science:
- Neurology
- Epileptology
- Stroke Medicine
Background:
- Poststroke seizures are a frequent complication of stroke in adults.
- Diagnosing seizures after stroke can be challenging due to overlapping symptoms with other conditions.
- Distinguishing between early and late poststroke seizures is crucial for management.
Purpose of the Study:
- To provide a comprehensive overview of poststroke seizures.
- To highlight diagnostic challenges and differential diagnoses.
- To discuss treatment strategies based on seizure timing.
Main Methods:
- Systematic review of literature on poststroke seizures.
- Analysis of diagnostic criteria and differential diagnoses.
- Evaluation of treatment approaches for early and late seizures.
Main Results:
- Early seizures (within 7 days) resemble acute symptomatic seizures and rarely recur.
- Late seizures (after 7 days) have recurrence risks similar to unprovoked seizures, necessitating long-term treatment.
- Differential diagnoses include movement disorders, syncope, and functional seizures.
Conclusions:
- Systematic diagnosis of poststroke seizures is essential, incorporating differential diagnosis.
- Classifying seizures as early or late informs treatment duration and medication choices.
- Long-term antiseizure medication may be required for late poststroke seizures.

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...
