|Change in muscle tone, frequent falls and increasing gait disorder||Epilepsy||Clinical examination (CE): bradykinetic motor-phenotype with increased muscle-tone, rigidity and spastic component, hypokinesia, cognitive decline and dystrophy.|
Further diagnostics (FD): comprehensive genetic diagnostics with chromosome analysis, analysis of array-based comparative genomic hybridization, analysis of methyl-CPG-binding-protein 2 gene. MRI: Narrowing of the caudate nucleus on both sides and subsequent gene testing with HD diagnosis.
Treatment attempts (TA): initially L-dopa/carbidopa attempt because of a suspected tyrosine hydroxylase deficiency.
Low-dosed pramipexole retard (bradykinesia) in combination with quetiapine (due to dopa-induced hallucination) lead to an improvement of movement disorder. Clobazam (anxiety- reducing and sleep- inducing) reduced ongoing sleep-disorder and had a positive effect on dystonia and the increased muscle tonus. Levetiracetam used for the treatment of epilepsy.
Course of disease (CD): use of dronabinol for palliative medical care with positive effects on muscle tonus, dystonia and body mass index (BMI).
|Problems in school, pronounced tremor with medium amplitude, gross and fine motoric function|| ||Anamnesis (A): early genetic testing because of positive family history, but retrospective symptoms already exist for the past 4 years.|
CE: initially hypomimia, lack of arm swinging, cognitive deficits.
Socio-medical aspects (SM): re-educated after diagnosis in a special school, which helped enormously. After depression with several suicidal attempts, irritable behavior, lack of impulsion, apathy, schooling no longer possible. Long-term psychiatric ward.
FD: electroencephalography (EEG): isolated bi-frontal sharp-wave-like activity and typical epilepsy potentials but no seizures observed while treatment with valproate (for stabilizing irritability).
TA: pramipexole (treatment of bradykinesia), venlafaxine (antidepressant), valproate retard, lithium (antidepressant and because of suicidal intent), quetiapine (antipsychotic). In adulthood, worsening of dystonia and spasticity (tiazidine initiated), swallowing and because of improved mood and absence of suicidal tendencies lithium stopped.
|Problems in school, depression, tremor|| ||A/CE: stressful family situation, father died due to suicide, sister died due to HD. Unspecific symptoms reported (depression, due to HD or family situation?). No genetic testing during the first visit. An additional tremor three months later indicated the genetic testing. |
FD: diagnostic of cranial MRI, awake, sleep EEG, electrocardiography (ECG) inconspicuous.
SM: arrangement with school, compensations for disadvantages helped remaining in class.
TA: psychotherapy, occupational therapy but no additional pharmacological therapy necessary at the present.
CD: mild bradykinesia in finger tapping without negatively influencing everyday life.
|Progressive motoric dysfunction, speech problems and problems in school||Epilepsy Severe expressive speech disorder||A: postnatal difficulties in thriving and swallowing.|
CE: bradykinesia in addition to hyperkinetic restlessness at night.
FD: cranial MRI (second year of life) revealed a reduction of brain volume (retrospective evaluated as physiological expansion of the external cerebrospinal fluid spaces in infancy).
TA: pramipexole retard (improved bradykinesia), valproate retard (positive influence on irritability), quetiapine (reduction of irritability and hallucinations), L-dopa/carbidopa (positive influence on rigidity)
CD: severe swallowing disorder, but percutaneous endoscopic gastrostomy (PEG) rejected.
|Attention deficit hyperactivity disorder (ADHD), problems in school, depression||Borderline personality disorder||A: initially presented to human genetic specialists by foster parents because of positive HD family history.|
CE: fine motor skills problems in initial testing.
FD: EEG with abnormal findings, without therapeutic consequences.
TA: refrain of therapy with dopamine agonists (e.g., pramipexole) due to optical hallucinations. Psychiatric symptoms more severe and main symptoms, motoric symptoms with slight tremor and rigidity. Low-dose risperidone (reduction of irritability and aggressive behavior), quetiapine, venlafaxine (as an antidepressant with only moderate success) and clozapine (because risperidone was not tolerated in higher doses). Clozapine improved emotional instability and psychosis but also tremor.
CD: earlier multiple suicide attempts (taking tablets, drinking solvents and swallowing razor blades). Patient is now an adult with a stable course and stabilized psychiatric symptoms in the course of the disease. Works in a workshop facility, accommodated in residential facility.
|ADHD, problems in school, behavioral problems|| ||A: initially diagnosed and treated as ADHD by unconnected children psychiatry, massive behavior problems. Before inconspicuous infancy (except for a slight delay in speech development). Methylphenidate (to improve attention problems) without lasting success. Patient then reconsidered as “not trainable”. |
CE: discreet bradykinesia, discreet intention tremor. Fine motoric skill disturbance and increased muscle tone of the lower extremities. Afterward molecular genetic HD diagnosis.
FD: pathological EEG without seizures.
SM: Aggressive behavior towards other children and adults. Massive crimes documented by police with aggression at the age of six years (documented rape attempt on a girl, robbery on an elderly woman and theft of a handbag in the age of 12) led to in- patient diagnostics in a child and youth psychiatry. Persistent behavioral problems with short attention span, lack of controllability for own behavior and verbal aggression persisted. Diagnosis however led to correction of expectations and consequently to relaxing of the loaded situation.
TA: risperidone (improved situation), zuclopenthixole (positive influence on irritability) stabilized conditions.
|Motor abnormalities increasingly occurred on the left side||Epilepsy||A/CE: Expressive speech development delay (received speech therapy). Increasing dystonia of the left foot, three years after the first motoric symptoms and following genetic HD testing. Increasing lethargy in the course of disease, dystrophic (weight < 3 percentile, length < 3 percentile). Saccadic eye movement, chameleon tongue, dystonia of left foot, tremor, bradykinesia, increased muscle tone and reflexes.|

Progressing exanthema (better after stopping of sifrol, Nexium, sirdalud). Amantadine, rotigotine lead to an improvement and better position of contract arms/ head. Due to ill skin loss of water with hypertonic dehydration. Topramax due to dystonia lead to an improvement of tremor. Additionally cannabinoids (Sativex-Spray©) leads to marked improvement of dystonia.
