Post-stroke seizures: risk factors and management after ischemic stroke.

Stroke is the leading cause of epilepsy in the elderly, ahead of degenerative diseases, tumors and head injuries. It constitutes a significant complication and a considerable comorbidity. The aim of our study was to describe the main factors implicated in the occurrence of post-stroke seizures and to identify the predictors of seizure recurrence. We conducted a descriptive, retrospective, monocentric study from January 2010 to December 2019, including patients who presented seizures following an ischemic stroke. We classified these seizures according to the International League Against Epilepsy (ILAE) into acute symptomatic seizures (ASS) if they occur within seven days of stroke, and unprovoked seizures (US) if they occur after more than one week. Clinical, para-clinical, therapeutic and follow-up data were statistically analyzed and compared. A total of 52 patients were included (39 men, 13 women; median age 55.1 years). 21 cases (40%) had ASS and the remaining 31 cases (60%) presented US. Young age below 65 years (71%), middle cerebral artery infarcts (83%), and cortical localization (87%) were the main factors depicted in our series. Parietal lobe infarction was more associated with US than ASS (p = 0.035). 24 patients (46%) have presented a recurrence of seizures (8/21 of ASS and 16/31 of US). The use of sodium valproate in monotherapy was identified as a recurrence risk factor (p = 0.013). In patients with post-stroke seizures, parietal lobe infarcts are more associated with US. We identified a higher risk of seizure recurrence in patients treated with sodium valproate monotherapy.

Early pregnancy-associated ischemic stroke during first trimester in a young woman: A case report.

Pregnancy-associated ischemic stroke is rare. The degree of the risk is the highest in the third trimester, but clinicians should be also wary from the beginning of the pregnancy as the risk still exists like demonstrated by our case.

Acute-onset chronic inflammatory demyelinating polyneuropathy with cranial nerves and respiratory tract involvement: A case report.

Sixteen percent of chronic inflammatory demyelinating polyneuropathy (CIDP) patients may present acutely like acute idiopathic demyelinating polyneuropathy (AIDP) the demyelinating form of GBS, developing in <8 weeks 2. This entity is classified as acute-onset CIDP (A-CIDP) which presents overlapping clinical and electrophysiological findings with GBS during early stages of disease, but followed with a chronic course beyond 2 months. Also, those who have three or more treatment-related fluctuations (TRF) are included under this term. Distinguishing between acute-onset chronic inflammatory demyelinating polyneuropathy (A-CIDP) and acute idiopathic demyelinating polyneuropathy (AIDP) may be difficult during early stages but is crucial in order to guide treatment strategies without delay. These two forms share some overlapping clinical and electrophysiological findings, including some severe clinical features such as cranial nerve and respiratory tract involvement making the diagnosis of A-CIDP more difficult.
