1/5. Gaucher's disease with Parkinson's disease: clinical and pathological aspects.

    The association between type 1 gaucher disease and PD has been reported in the literature. The clinical picture is characterized by the predominance of bilateral akinetic-rigid signs and poor response to levodopa therapy. The authors describe four patients (two siblings) with type 1 gaucher disease presenting with the following signs of typical PD: asymmetric onset of rigidity, resting tremor, bradykinesia, and a favorable response to Parkinson therapies.

2/5. A compensatory mechanism in unilateral akinetic-rigid syndrome: an fMRI study.

    The motor mechanisms of a patient with unilateral hand clumsiness in the early stages of akinetic-rigid syndrome were assessed by functional magnetic resonance imaging (fMRI). Movements of the unaffected hand produced activation in the contralateral sensorimotor cortex (SMC) and ipsilateral SMC and superior parietal lobule (SPL). The affected hand activated the bilateral SMCs, supplementary motor areas, and SPLs. We speculated that the bilateral activation indicated recruitment of a pre-existing bilaterally organized large-scale neural network to perform the motor task.

3/5. Neonatal rigid-akinetic syndrome and dentato-olivary dysplasia.

    This report describes a male infant who presented since birth with rigidity and hypokinesia. Severe developmental delay, episodic central hypoventilation, and drug-resistant epilepsy progressively added to the extrapyramidal signs in the following months and led to the patient's death at 10 months of age. Neuroradiologic and neurometabolic evaluations were negative. Normal cerebrospinal metabolites excluded a defect in dopamine metabolism, and treatment with levodopa failed to improve his motor symptoms. Neuropathologic findings demonstrated dentato-olivary dysplasia. While isolated dentato-olivary dysplasia has been described in a few cases of Ohtahara syndrome, to our knowledge, the association with infantile parkinsonism has not been previously reported.

4/5. Acute and long-term effects of subthalamic nucleus stimulation in Parkinson's disease.

    In animal models of Parkinson's disease (PD), it is postulated that the excessive output from the subthalamic nucleus (STN) plays a critical role. Selective lesions or high frequency electrical stimulation of the STN can alleviate parkinsonian symptoms in MPTP-treated monkeys. We decided to carry out STN stimulation in patients suffering from severe akinetic forms of PD. After approval of the institutional ethical committee, we operated on a parkinsonian patient aged 51, suffering for 8 years from a strongly disabling akinetorigid form of PD, complicated by an on-off effect (Hoehn and Yahr stage 5 in the worst-off motor phase). Stereotactic surgery was done on one side under local anesthesia. The theoretical target was chosen according to stereotactic atlases, based on ventriculographic landmarks such as anterior and posterior commissures (AC and PC). The final position of the chronic electrodes was optimized using electrophysiological recording and stimulation along with clinical assessment and surface EMG of agonist and antagonist muscles of the examined limbs. A spontaneous increase in neuronal activity was recorded in an area located 2-4 mm under the level of the intercommissural plane, 10 mm from the midline, at mid-distance between AC and PC. Within the same place, a 130-Hz stimulation induced acute and reversible akinesia alleviation mainly on the contralateral limbs, comparable to that obtained with dopaminergic drugs. No dyskinesia, such as hemiballism, was induced by introduction of electrodes or by stimulation. Then a long-term quadripolar DBS Medtronic electrode was inserted in this area. Studies of the effects of chronic stimulation were extensively performed to determine the best spatiotemporal and electrical stimulation variables.(ABSTRACT TRUNCATED AT 250 WORDS)

5/5. Episodically remitting akinetic mutism following subarachnoid hemorrhage.

    akinetic mutism is characterized by alertness with near complete absence of volitional activity. The authors report a case of episodically remitting akinetic mutism following subarachnoid hemorrhage.
