Gait abnormalities in people with Dravet syndrome: A cross-sectional multi-center study

In reviews of Dravet syndrome, statements about gait are usually very generalized, along the lines of: ” by the age of 13 years, up to 80% of people with Dravet syndrome walk with a crouch gait”. However, it would be useful to have a more specific, and detailed, description, which is what the current paper …

Dravet syndrome and parkinsonism: A case report investigating the dopaminergic system

This paper was interesting because one doesn’t see too many reports focused on adult Dravet patients. It has been found that Parkinsonism is a motor condition that often develops in adults with Dravet syndrome. However, it is not well understood how Dravet syndrome, in particular dysfunction of the NaV1.1 sodium channel, is connected to the …

Engineering brain activity patterns by neuromodulator polytherapy for treatment of disorders

This article is interesting for a couple of reasons. First, it describes the use of zebrafish as a model for Dravet syndrome. Zebrafish have become very useful in medical research. They are small, and easy and inexpensive to maintain and employ in drug response studies, especially in comparison to mice. Of course, although they share …

NaV1.1 and NaV1.6 selective compounds reduce the behavior phenotype in a novel zebrafish model for Dravet Syndrome

Dravet syndrome is caused by loss-of-function mutations in the SCN1A gene, which codes for the alpha subunit of the NaV1.1 sodium channel. However, there are other sodium channels, and it is known that gain-of-function mutations in SCN8A, the gene that codes for the alpha subunit of the NaV1.6 sodium channel, can lead to severe epileptic …

The Efficacy of Ketogenic Diet in 60 Chinese Patients With Dravet Syndrome

This was a retrospective study, gathering information on Dravet patients who, over the last nine years, had followed a strict ketogenic diet for at least 12 weeks. In total, there were 60 children identified. The duration of their ketogenic diets ranged from 12 weeks to 54 months, with a median duration of 44 weeks. In …

Potentiating α2 subunit containing perisomatic GABAA receptors protects against seizures in a mouse model of Dravet syndrome

Many of the drugs used to treat Dravet Syndrome work by interacting with GABAA receptors.  Each GABAA receptor is composed of subunits, and there are different versions of receptors depending on which subunits they have. Drugs have unwanted side-effects, and it is worth asking: if we hit just one specific kind of GABAA receptor, instead …
