Juvenile Huntington S Disease

The Special Issue “Juvenile Onset Huntington’s Disease” highlights the growing interest in understanding the unique aspects of this ultra-rare disorder. After decades of research, gene therapy trials are underway for Adult Onset Huntington’s Disease (AOHD). However, patients with Juvenile Onset Huntington’s Disease (JOHD) are often excluded from these efforts, leaving many questions regarding its phenomenology. The current issue includes seven articles spanning work on the difficult emotional experiences of parents of children with JOHD; a review of the clinical manifestations of JOHD; behavioral issues in JOHD; CAG repeat and age of motor onset; autonomic nervous system dysfunction; and abnormality in MRI metabolic markers. Finally, a review of the therapeutic advances is included, highlighting future possibilities of clinical trials in JOHD subjects. The HD community—patients, family members at-risk for HD, caregivers, health-care professionals and scientists—is keen on expanding our understanding of JOHD. In the flurry of research on AOHD, those with JOHD were seemingly ‘left behind.’ The study of patients who are afflicted early in life with HD has become imperative, with this Special Issue representing just the beginning of the required effort to address this urgent need.

Huntington's disease (HD) is an inherited progressive neurodegenerative disorder. Although onset of Huntington's Disease usually occurs in adulthood, the age of onset of the condition is extremely variable with approximately 5-10% of cases having an onset of less than 20 years, or Juvenile Huntington's Disease (JHD). While JHD shares many of the clinical features of adult HD (e.g., chorea and personality disorders), patients with JHD often experience additional problems including seizures, dystonia and Parkinsonism. Diagnosis in patients with JHD is often delayed because of the failure of clinicians to recognise the characteristic features of the condition. While several textbooks have been published on HD, no books have been published to date focussing solely on the juvenile onset form of the disease. This book summarises, for the first time, the clinical and scientific knowledge available on JHD. It also collects together accounts from families affected by the condition, putting the clinical and scientific chapters into context. Edited by members of the working group on Juvenile Huntington's Disease within the European Huntington Disease Network (EHDN), this book forms the first comprehensive text on JHD and is of interest to neurologists, geneticists, academic/research scientists and other healthcare professionals.

Huntington's disease affects 1 person in 10,000 but this figure is an underestimate because the immediate carer, spouse/partner and the close relatives at risk of developing this condition in the future are also affected. The new edition has been revised to include important new developments that have occurred in the field in recent years.

This monograph describes the progress in neuropathological HD research made during the last century, the neuropathological hallmarks of HD and their pathogenic relevance. Starting with the initial descriptions of the progressive degeneration of the striatum as one of the key events in HD, the worldwide practiced Vonsattel HD grading system of striatal neurodegeneration will be outlined. Correlating neuropathological data with results on the functional neuroanatomy of the human brain, subsequent chapters will highlight recent HD findings: the neuronal loss in the cerebral neo-and allocortex, the neurodegeneration of select thalamic nuclei, the affection of the cerebellar cortex and nuclei, the involvement of select brainstem nuclei, as well as the pathophysiological relevance of these pathologies for the clinical picture of HD. Finally, the potential pathophysiological role of neuronal huntingtin aggregations and the most important and enduring challenges of neuropathological HD research are discussed.

This is the story of Breanna. Breanna is quite an exceptional 8 year old. She loves singing, movies, and princess dresses, and everywhere she goes, she takes her million-dollar smile with her. One day, she notices her body doing things she doesn't expect or understand. After a trip to the doctors, she learns that she is living with Juvenile Huntington's Disease, a genetic condition affecting the brain. Rather than letting it get her down, Breanna shows everyone just what it means to be a positive force in the world. Join her as she teaches the people around her what it really means to be brave, and helps them to find their smile even when it seems like nothing is going their way.

Hyperkinetic movement disorders comprise a range of diseases characterized by unwanted and uncontrollable, or poorly controllable, involuntary movements. The phenomenology of these disorders is quite variable encompassing chorea, tremor, dystonia, myoclonus, tics, other dyskinesias, jerks and shakes. Discerning the underlying condition can be very difficult given the range and variability of symptoms. But recognizing the phenomenology and understanding the pathophysiology are essential to ensure appropriate treatment. Hyperkinetic Movement Disorders provides a clinical pathway for effective diagnosis and management of these disorders. The stellar international cast of authors distils the evidence so you can apply it into your practice. The judicious use of diagnostic criteria algorithms rating scales management guidelines Provides a robust framework for clear patient management. Throughout the text, QR codes* provide smartphone access to case-study videos of hyperkinetic symptoms.
