The PDE3 database is an important new resource for drug repurposing research in epilepsy.

Epilepsy has a negative impact on quality of life in patients with benign meningioma. AED use is correlated with impaired QoL and raised LAEP scores, suggesting that AEDs and adverse effects may have led to impaired QoL in our meningioma patients with epilepsy. The severity of epilepsy in our meningioma population was comparatively mild; therefore, a more conservative approach to AED therapy may be indicated in an attempt to minimize adverse effects.

Alpha-methylacyl-CoA racemase (AMACR) deficiency is a rare peroxisomal disorder causing pristanic acid accumulation. Only 16 cases have been described so far. A female in her seventh decade presented with episodes of dysphasia, headache and sensory disturbance inconsistent with migraine, epilepsy or transient ischaemic attack. An MRI demonstrated unusual changes in the pons, red nuclei, thalami and white matter. Mitochondrial disease was suspected but detailed testing was negative. After eight years of symptoms, she developed a febrile encephalopathy with hemispheric dysfunction, focal convulsive seizures and coma. Her condition stabilised after one month. Lacosamide was continued for seizure prevention. The diagnosis remained elusive until whole genome sequencing revealed AMACR deficiency. Pristanic acid levels were highly elevated and dietary modification was recommended. Genetic peroxisomal disorders can present in older age; our patient is the oldest in the AMACR deficiency literature. Novel features in our case include central apnoea, dystonia and rapid eye movement behaviour disorder.
