Analysis of the neurologic symptomatology in 22 patients with Niemann-Pick disease type C revealed 3 phenotypes: (1) an early-onset, rapidly progressive form associated with severe hepatic dysfunction and psychomotor delay during infancy and later with supranuclear vertical gaze paresis, ataxia, marked spasticity, and dementia; (2) a delayed-onset, slowly progressive form heralded by the appearance, usually in early childhood, of mild intellectual impairment, supranuclear vertical gaze paresis, and ataxia, and later associated with dementia and, variably, seizures and extrapyramidal deficits; (3) a late-onset slowly progressive form distinguished from the 2nd pattern by later age of onset (adolescence or adulthood) and a much slower rate of progression. The existence of the 1st and 2nd phenotypes within the same sibship suggests that they are variant expressions of the same clinicopathologic disorder. Niemann-Pick disease type C should be considered not only in infants and children who present with organomegaly and a progressive neurodegenerative course, but also in adolescents and adults who have insidiously progressive neurologic dysfunction and only slight organomegaly. Associated with the disease is a marked deficiency in the ability of cultured fibroblasts to esterify exogenously supplied cholesterol. Assay of this deficiency is particularly useful for confirming the diagnosis in patients with atypical presentation.

We reported a 32-year-old man with general paresis. He showed slowly progressive bradykinesia and recent memory loss. Argyll Robertson pupils were not present. Muscle strength and sensations were normal except for slight vibratory disturbance. Tendon reflexes were slightly exaggerated. MMSE, HDS-R and WAIS-R scores showed the intellectual impairment. His laboratory investigations revealed elevated both TPHA and FTA-ABS titers in the serum and the CSF. The CSF contained leukocytosis (25/mm3) and protein 80 mg/dl. Cranial CT and MRI demonstrated diffuse cortical atrophy. SPECT revealed marked reduction of the blood flow in bilateral cerebral hemisphere. Cerebral angiography revealed moderate stenosis of the major vessels. The diagnosis of neurosyphilis (general paresis) was made and the treatment of intravenous benzyl penicillin potassium 24 million units per day was started. After 6 weeks of the treatment, the clinical signs (includes MMSE, HDS-R and WAIS-R scores) and the findings of SPECT and cerebral angiography showed improvement. Although the cell count and protein in the CSF became decreased, the titers of TPHA and FTA-ABS in the serum and the CSF were not decreased. Neurosyphilis should always be considered in a etiologically unknown case with bradykinesia and dementia.

In daily clinical practice we noticed that patients with intellectual impairment spontaneously flex the elbow within a few seconds of the forearm being manipulated during routine examination of spasticity of the muscles in the upper extremities. We termed this phenomenon elbow flexion response (EFR), and prospectively studied it in 229 patients who underwent in-hospital rehabilitation following brain damage. Evaluation of each patient included EFR, patient profile, ability to communicate, scores on three parameters from various intelligence tests, scores on seven parameters testing primitive reflexes, and scores on three parameters describing personality. We investigated for relationships among these parameters. Consequently, although EFR rarely have a statistical association with the varied profiles of patients, patients with bilateral lesion or bilateral paresis demonstrated significantly more marked EFR than those with unilateral lesion or unilateral paresis. Patients with involvement of the frontal lobe showed significantly more marked EFR than those without damage in this area. Elbow flexion responses occurred significantly more frequently in relation with lower scores on intelligence and occurred with significantly higher frequency in conjunction with the more marked appearance of conventional primitive reflexes. Therefore, we conclude that EFR have a strong association with intelligence and with the existence of frontal lobe lesion, and their mode of clinical presentation parallels that of primitive reflexes particularly that of the grasp reflex. We propose that EFR could be referred as a variation of the grasp reflex occurring in the more proximal or axial part of the body.

Acute lymphoblastic leukemia (ALL) is one of the most common malignancies of childhood, which is treated with high doses of methotrexate (MTX), as it crosses the blood-brain barrier and can be administered intravenously and via intrathecal route to eradicate leukemic cells from central nervous system (CNS). Additionally, high doses of MTX not only prevent CNS recurrence but also hematologic relapses. Although, standard treatment protocol for ALL includes multimodality therapy, MTX is usually associated with neurotoxicity and affects periventricular deep white matter region. Methotrexate-induced 'acute toxic leukoencephalopathy' has varying clinical manifestations ranging from acute neurological deficit to seizures or encephalopathy. Diffusion weighted magnetic resonance imaging (DW-MRI) is widely available and routinely used in clinical practice to identify acute stroke and also to distinguish acute stroke from non-stroke like conditions. We report a local teenage Chinese girl who developed 2 discrete episodes of left upper and lower limb weakness with left facial nerve paresis after receiving the 2 nd and 3 rd cycle of high dose of intravenous and intrathecal methotrexate, without having cranial irradiation. After each episode of her neurological deficit, the DW-MRI scan showed focal restricted diffusion in right centrum semiovale. Her left sided focal neurological deficit and facial nerve paresis almost completely subsided on both these occasions within 3 days of symptom onset. Follow-up DW-MRI, after her neurological recovery, revealed almost complete resolution of previously noted restricted diffusion in right centrum semiovale, while the lesion was not evident on concurrent T2W (T2-weighted) and FLAIR (Fluid-Attenuated Inversion recovery) sequences, nor showed any post contrast enhancement on post gadolinium enhanced T1W (T1-weighted) sequences. No residual neurological deficit or intellectual impairment was identified on clinical follow up over a 2 year period.
