SummarySuccinic semialdehyde dehydrogenase (SSADH) deficiency, a disorder of GABA degradation with subsequent elevations in brain GABA and GHB, is a neurometabolic disorder with intellectual disability, epilepsy, hypotonia, ataxia, sleep disorders, and psychiatric disturbances. Neuroimaging reveals increased T2-weighted MRI signal usually affecting the globus pallidus, cerebellar dentate nucleus, and subthalamic nucleus, and often cerebral and cerebellar atrophy. EEG abnormalities are

The pace of discovery in biochemistry and genetics and its effect on clinical medicine places new curricular challenges in medical school education. We sought to evaluate students' understanding of neurogenetics and its clinical applications to design a pilot curriculum into the clinical neurology clerkship. We utilized a needs assessment and a written examination to evaluate the genetics knowledge of 81 third- and fourth-year medical students. The needs assessment surveyed students' self-perceptions of their own understanding of basic and clinically related genetic principles and clinical skills, as well as the most effective educational methods. Medical students reported more competence with basic science learned during the preclinical years than clinical concepts, and they demonstrated relatively low knowledge levels in clinical neurogenetics concepts on the examination, with an average of 29% correct on questions pertaining to genetic counseling compared with 82% correct with regard to inheritance patterns. Common, cross-specialty clinical skills were attained (e.g. internet search, family histories), while at least half of students reported minimal understanding or awareness of key genetics websites (e.g. OMIM) and indications for support group recommendations and genetics referrals. Teaching these more specific genetics skills and concepts needs to be emphasized in the clinical curriculum.

Most children with paediatric neurotransmitter diseases have global functional deficits secondary to central nervous system damage. Paediatric physiatrists, working in conjunction with a multi-disciplinary team, help to improve physical function by normalizing muscle tone and improving body position. Components of spasticity, rigidity, and dystonia may all need to be considered in a comprehensive treatment programme. Complications of disordered tone include skin breakdown, pain, sleep disturbance, and dysphagia. With an integrated approach to use of medications and equipment as well as implementation of therapy and therapeutic exercise, physiatrists can help maximize functional independence for children with this group of disorders. Pharmacological treatment includes GABA-agonists including baclofen and benzodiazepines, alpha-2 adrenergic agonists, L: -dopa and dopaminergic agents, and dantrolene. Intrathecal baclofen may be used in patients refractory to these medications. In addition, physicians may utilize botulinum toxin, phenol, or surgical interventions such as selective dorsal rhizotomy or tendon lengthening. Pharmacological treatment must be used in conjunction with appropriate adaptive equipment in order to maximize therapeutic benefit. Focus on function in an attempt to increase independence is targeted to improve the child's quality of life. We present a framework and rationale to the management of the functional consequences of the paediatric neurotransmitter diseases.
