ILAE/IBE/WHO Global Campaign Against Epilepsy: a partnership that works.

PURPOSE OF REVIEW: Epilepsy can hijack the lives of many persons of all ages. It is an unpredictable disease that can manifest itself in seizures, brain damage and cognitive and psychiatric disabilities, although some people with epilepsy can have a relatively normal life. People with epilepsy are among the most vulnerable in any society because the disease is misunderstood and often stigmatizing. Thus, many patients and their families are reluctant to admit that they suffer from epilepsy. This in turn affects public policy in terms of patient care, early diagnosis, medical research, advocacy, cure and their very lives. RECENT FINDINGS: A survey to evaluate the results of Global Campaign Against Epilepsy activities on a national level was performed in 2009. Data from the demonstration projects have already changed the public policies in several countries. SUMMARY: On the occasion of the launch of phase II of the Campaign, the WHO Director General stated: 'The collaboration between the IBE, ILAE and WHO has shown that when people with different backgrounds and roles come together with a shared purpose, creativity is released and expertise is used in innovative and constructive ways'. Indeed, this partnership led to many activities and all over the world to many people 'standing up for epilepsy'.

Autism, fever, epigenetics and the locus coeruleus.

Some children with autism spectrum disorders (ASD) exhibit improved behaviors and enhanced communication during febrile episodes. We hypothesize that febrigenesis and the behavioral-state changes associated with fever in autism depend upon selective normalization of key components of a functionally impaired locus coeruleus-noradrenergic (LC-NA) system. We posit that autistic behaviors result from developmental dysregulation of LC-NA system specification and neural network deployment and modulation linked to the core behavioral features of autism. Fever transiently restores the modulatory functions of the LC-NA system and ameliorates autistic behaviors. Fever-induced reversibility of autism suggests preserved functional integrity of widespread neural networks subserving the LC-NA system and specifically the subsystems involved in mediating the cognitive and behavioral repertoires compromised in ASD. Alterations of complex gene-environmental interactions and associated epigenetic mechanisms during seminal developmental critical periods are viewed as instrumental in LC-NA dysregulation as emphasized by the timing and severity of prenatal maternal stressors on autism prevalence. Our hypothesis has implications for a rational approach to further interrogate the interdisciplinary etiology of ASD and for designing novel biological detection systems and therapeutic agents that target the LC-NA system's diverse network of pre- and postsynaptic receptors, intracellular signaling pathways and dynamic epigenetic remodeling processes involved in their regulation and functional plasticity.

Endocannabinoid-mediated long-term plasticity requires cAMP/PKA signaling and RIM1alpha.

Endocannabinoids (eCBs) have emerged as key activity-dependent signals that, by activating presynaptic cannabinoid receptors (i.e., CB1) coupled to G(i/o) protein, can mediate short-term and long-term synaptic depression (LTD). While the presynaptic mechanisms underlying eCB-dependent short-term depression have been identified, the molecular events linking CB1 receptors to LTD are unknown. Here we show in the hippocampus that long-term, but not short-term, eCB-dependent depression of inhibitory transmission requires presynaptic cAMP/PKA signaling. We further identify the active zone protein RIM1alpha as a key mediator of both CB1 receptor effects on the release machinery and eCB-dependent LTD in the hippocampus. Moreover, we show that eCB-dependent LTD in the amygdala and hippocampus shares major mechanistic features. These findings reveal the signaling pathway by which CB1 receptors mediate long-term effects of eCBs in two crucial brain structures. Furthermore, our results highlight a conserved mechanism of presynaptic plasticity in the brain.
