    Study Notes

    Neurological Disorders

    • Neurological disorders affect the nervous system and are a significant global burden
    • Examples include stroke, neonatal encephalopathy, cerebrovascular disease, neurodegenerative disorders, and rare diseases
    • The most common causes of neurological disorders include oxygen deprivation and slow progressive loss of neurons

    Burden of Neurological Disorders

    • Neurological disorders are the largest disease burden worldwide
    • Australian Institute of Health and Welfare states neurological disorders are a significant public health concern in Australia
    • Much of the burden is carried by permanent disabilities and early mortality

    Current Research in Brain and Developmental Disorders

    • Recent research has focused on cerebrovascular disease, neurodegenerative disorders, and rare diseases
    • Primary areas of research include prevention and recovery from stroke
    • Biomarkers for early diagnosis are being investigated for neurodegenerative disorders to improve treatment outcomes
    • De novo variants are a major contributor to rare neurological diseases, often causing disorders in infancy or childhood

    Research into Epilepsy

    • Epilepsy research focuses on identifying the molecular cause of disorders to enable precision medicine
    • The complexity of epilepsy syndromes requires individualised treatment plans based on genetic and clinical factors
    • Research has moved towards a precision medicine approach that tailors treatment to the individual patient's molecular profile

    Research Approaches

    • Research involves patient sequencing to identify genes associated with the disease
    • In silico analysis helps determine pathogenicity of gene variants
    • Physiological and functional analysis investigates the implications of gene variants
    • Cohort drug analysis examines drug efficacy in different genetic populations
    • Preclinical drug development focuses on creating targeted treatments
    • Clinical trials are conducted to evaluate the safety and effectiveness of new drugs in human populations
