Summary
Ictal coughing, a rare seizure symptom, was documented in 0.28% of patients. This symptom can indicate either epilepsy or psychogenic nonepileptic seizures (PNES).
Area of Science:
- Neurology
- Epileptology
Background:
- Ictal coughing is an uncommon manifestation observed during seizures.
- Understanding its occurrence and clinical characteristics is crucial for diagnosis.
Purpose of the Study:
- To describe patients experiencing ictal coughing.
- To estimate the frequency of ictal coughing.
- To characterize clinical features and differential diagnoses of ictal coughing.
Main Methods:
- Retrospective review of long-term video-electroencephalogram (EEG) reports over a 7-year period.
- Identification of patients with documented ictal coughing at an epilepsy monitoring unit (EMU).
Main Results:
- Seven out of 2487 patients (0.28%) exhibited ictal coughing.
- Four patients had epilepsy (focal onset), and three had psychogenic nonepileptic seizures (PNES).
- Ictal coughing was not linked to specific seizure localization or lateralization in epilepsy cases.
Conclusions:
- Ictal coughing is a rare finding in EMU evaluations.
- Differential diagnoses include epilepsy and PNES.
- Epileptic ictal coughing is associated with focal epilepsy.

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

4.7K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
