A 4 year old girl with normal birth history and development with the exception of an episode of maternal hemiplegia during pregnancy. There is no significant family history of any neurological issues. Her medical history is unremarkable except for celiac disease which is treated with a gluten-free diet.
An half a year ago she developed scarlet fever and began to have episodes of right hand tremor lasting 6 seconds with no alteration of consciousness. One month later she had more events and was taken to the local ED where an EEG was performed.
72-year-old female developed progressive dysarthria and dysphagia. Her doctor describes her speech difficulty as “Spastic dysarthria with slow and nasal speech" and noticed decreased mobility in the tongue and palate. She underwent multiple investigations and started Rilutek. Since there is no biologic marker for ALS, the expert suggests further testing that is focused on trying to rule out other disorders and show diffuse lower motor neuron involvement
71-year-old female developed progressive dysarthria and dysphagia. Her doctor describes her speech difficulty as “Spastic dysarthria with slow and nasal speech" and noticed decreased mobility in the tongue and palate. She underwent multiple investigations and started Rilutek. The differential diagnosis of isolated swallowing and speaking difficulties include: Early motor neuron disease, Cranial neuropathies, Myopathies, Neuromuscular junction disorders and Neurodegenerative movement disorders.
5-year-old boy was diagnosed with neurofibromatosis type 1 (NF1) eight months after birth. He has displayed café-au-lait spots, axillary freckling, macrocephaly, sphenoid dysplasia, brain hamartomas, right temporal arachnoid cyst, and optic glioma. Visual evoked potentials showed evidence of bilateral functional deficit.
71-year-old female developed progressive dysarthria and dysphagia. She underwent multiple investigations and started Rilutek. Her EMG study does not meet published criteria for the electrophysiologic diagnosis of motor neuron disease. In the expert's opinion, a definite diagnosis is not possible at the present time, and there would be utility in repeating clinical and electrophysiologic testing. The expert also recommends to perform pulmonary function testing.
Child with progressive exotropia secondary to the profound vision loss that appears to be to an optic neuropathy. The expert recommends to obtain additional studies in order to exclude potential diagnosis such as glioma, pathological disc edema, optic nerve drusen or dominant optic atrophy OPA-1 gene related.
21-year-old female with an acute onset of a unilateral sixth cranial nerve deficit. Brain MRI showed at least a dozen white matter lesions, one of them contrast-enhancing. Sensory evoked potentials showed a bilateral increase in latency. Multiple sclerosis was diagnosed, and the patient was treated by corticosteroids, followed by improvement of symptoms. The first follow-up revealed no focal neurological signs with a history of a transitory unilateral lower limb hyposthenia. On the second visit, a horizonto-rotatory nystagmus and irregular paraesthesia in the right toes are documented.
