The present invention relates to the use of cannabidiol (CBD) in the treatment of focal seizures. In one embodiment the patients suffering from focal seizures are children and young adults. CBD appears particularly effective in reducing focal seizures in patients suffering with etiologies that include: Lennox-Gastaut Syndrome; Tuberous Sclerosis Complex; Dravet Syndrome; CDKL5; Neuronal ceroid lipofuscinoses (NCL); febrile infection related epilepsy syndrome (FIRES); Aicardi syndrome and brain abnormalities in comparison to other seizure types. Significantly CBD additionally is very effective in the reduction of a sub-type of focal seizures, focal seizures with impairment.

Described herein are methods of treating epilepsy or status epilepticus, e.g., convulsive status epilepticus, e.g., early status epilepticus, established status epilepticus, refractory status epilepticus, super-refractory status epilepticus, e.g., super-refractory generalized status epilepticus; non-convulsive status epilepticus, e.g., generalized status epilepticus, complex partial status epilepticus; generalized periodic epileptiform discharges; periodic lateralized epileptiform discharges; a seizure, e.g., acute repetitive seizures, cluster seizures, the method comprising administering to the subject a neuroactive steroid.

The present invention relates to a compound of formula (1) wherein Q.sup.1 is halogen atom, Q.sup.2 is hydrogen atom, etc., X, Y, and Z are nitrogen atom or oxygen atom, and R.sup.1 has a given structure, or a pharmaceutically acceptable salt thereof, and a medicament comprising the compound for treating and/or preventing a disease such as epilepsy. ##STR00001##

The present invention relates to the use of cannabidiol (CBD) in the treatment of epilepsy which results from mutation of the GRIN2A gene. The CBD used is in the form of a highly purified extract of cannabis such that the CBD is present at greater than 98% of the total extract (w/w) and the other components of the extract are characterised. In particular the cannabinoid tetrahydrocannabinol (THC) is present in an amount of from 0.02 to 0.1% (w/w). In an alternative embodiment the CBD may be in a synthetic form. In use the CBD may also be used concomitantly with one or more other anti-epileptic drugs (AED). The CBD may be formulated for administration separately, sequentially or simultaneously with one or more AED or the combination may be provided in a single dosage form. Where the CBD is formulated for administration separately, sequentially or simultaneously it may be provided as a kit or together with instructions to administer the one or more components in the manner indicated. It may also be used as the sole medication, i.e. as a monotherapy.

wherein all radicals are as defined in the application and claims. The compounds according to the invention are positive allosteric modulators of metabotropic receptors—subtype 2 (“mGluR2”) which are useful for the treatment or prevention of neurological and psychiatric disorders associated with glutamate dysfunction and diseases in which the mGluR2 subtype of metabotropic receptors is involved. In particular, such diseases are central nervous system disorders selected from the group of anxiety, schizophrenia, migraine, depression, and epilepsy. The invention is also directed to pharmaceutical compositions and processes to prepare such compounds and compositions, as well as to the use of such compounds for the prevention and treatment of such diseases in which mGluR2 is involved.

The present invention relates to the use of cannabidiol (CBD) for the treatment of seizures associated with rare epilepsy syndromes. In particular the seizures associated with rare epilepsy syndromes that are treated are those which are experienced inpatients diagnosed with PCDH19 Epilepsy. In a further embodiment the types of seizures include tonic-clonic seizures. Preferably the dose of CBD is between 5 mg/kg/day to 50 mg/kg/day.
