Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with undetermined etiology that primarily involves the motor neurons in the cerebral cortex, brainstem and spinal cord.
There is no cure and the mean duration of survival is 2-5 years without tracheostomy and ventilator support.
Clinical hallmarks of ALS are: presence of upper & lower motor neuron features involving the brainstem and spinal cord and progressive limb weakness, respiratory insufficiency, spasticity, hyperreflexia, and bulbar symptoms such as dysarthria and dysphagia.

Long‐term treatment with perampanel in the adjunctive setting appears to provide improved seizure control without raising new safety/tolerability signals in patients with epilepsy, particularly those with secondarily generalized seizures at baseline, according to the results of an open-label extension of phase III trials.

The addition of highly purified cannabidiol (CBD) into an antiepileptic regimen led to reductions in convulsive seizure rates in children with Dravet syndrome (DS), the GWPCARE2* study has shown.

High rather than low levels of neonatal 25(OH)D3 pose an increased risk of incident epilepsy in early childhood, a finding that may be attributed to chance, confounding, or late gestational vitamin D exposure, according to a study.

In the treatment of idiopathic generalized epilepsy, switching from valproate to other antiepileptic drugs due to potential childbearing issues may prove detrimental, heightening the risk of poor seizure control, as shown in a recent study.
