Both Kayser-fleischerring and choreic movement were absent. Deep reflexes were brisk and Babinski’s sign was absent. Speech and muscle tone was normal. Blood routine and smear, liver function, iron and copper metabolism were of normal range.[bmcneurol.biomedcentral.com]
One patient had progressive cerebellarsigns associated with cerebellar atrophy on cerebral magnetic resonance imaging before signs suggestive of HD appeared.[ncbi.nlm.nih.gov]
Late chorea tends to involve proximal muscle groups associated features 50% - generalized tonic-clonic seizures 50% - cerebellarsigns 20% - oculomotor apraxia gait disturbance more rapid course in children than in adults average of 8 years till death[endoflifecare.tripod.com]
In juvenile HD the movement disorder, rather than chorea, is primarily tremor, bradykinesia and dystonia. 3–5 In juvenile HD cerebellarsigns, epilepsy, myoclonus and spasticity may also occur.[bmjopen.bmj.com]
Patient had resting and actiontremors. Investigation including haemogram, ESR, peripheral blood film, hepatic and renal function tests were normal. Ophthalmic examination did not show Kayser Fleischer ring.[neurologyindia.com]
After 5 year of onset of these symptoms, she lost interest in family members and her friends. 6 months prior to admission she developed slowness of gait and initiation and performance of routine work along with finetremors all over the body.[neurologyindia.com]
She had a slow and monotonousspeech with diminished word output. Cogwheel rigidity was present in all four limbs with flexor planters. Glabellar tap, snout and pout reflexes were positive. Eye movements were also affected.[neurologyindia.com]
The generalizedseizures experienced by HD children are usually what are called tonic-clonic seizures. Generalized tonic-clonic seizures (or grand mal seizures) consist of both tonic and clonic phases.[web.stanford.edu]
Epileptiform discharges include generalized polyspike and slow-wave complex, spike and slow-wave complex, multifocal spikes and focalspikes.[e-jmd.org]

[…] disease gene test Susanne A Schneider, Ruth H Walker and Kailash P Bhatia Huntington's disease (HD), which is caused by a triplet-repeat expansion in the IT15 gene (also known as huntingtin or HD), accounts for about 90% of cases of chorea of genetic etiology[hdlf.org]
The further investigation should be focus on the relationship between TS and HD, especially at the level of pathophysiology and genetic etiology.[bmcneurol.biomedcentral.com]

Anticonvulsant drugs are usually prescribed to help prevent and control the seizures that occur in children with juvenile HD.[web.stanford.edu]
This may prevent a rapid deterioration of the condition, and help sustain the quality of life. Patients diagnosed with HD may live anywhere between 10-30 years following the onset of symptoms.[dovemed.com]
Physical and occupational therapy may also be helpful for temporarily easing these symptoms, developing strategies for moving around, and preventing falls.[rarediseases.info.nih.gov]
