... les 49.5%, age range 16–90, 30% referred by General Practices (GPs), 59.1% by the Accident & Emergency Department (A&E) and 10.9% by other hospital wards, 24.5% did not attend (DNA) the clinical appointment. Females who did not attend were significantly older than males (49.8 years old vs 39.7; p = 0.007). Among those who attended the clinical appointment, 17% were diagnosed first unprovoked seizure, 12.4% acute symptomatic seizure and 28.9% epilepsy. These patients were referred mainly by A&E while GPs referred seizure mimics especially non-epileptic attack disorder (NEAD) and syncope. Patients with NEAD were significantly younger than those with seizures (29.4 years old vs 44.2; p < 0.001) and had a previous psychiatric history (72.7% vs 16.8%; p < 0.001). The proportion of seizure mimics was similar in the older sample group (> 65 years). Regarding acute symptomatic seizures, 33.3% were alcohol-related, 20.8% acute brain insults and 12.5% drug-related (always overdose). Conclusions. 1 in 4 patients referred to a FSC does not attend the clinical appointment, especially older females. More than 1 in 3 cases represent seizure mimics and are referred mainly by GPs.
