P587L2
| diabetes mellitus 2, congestive heart failure, hypothyroidism, hypertension, depression with psychotic features and gastric bypass surgery. gait difficulties, cognitive impairment, ophthalmoplegia, resting tremor and peripheral neuropathy. Shooting pains and numbness in her lower extremities, occasional rectal incontinence. Presyncopal dizziness. Complicated diabetic retinopathy. sensory ataxia secondary to a sensorimotor polyneuropathy, chronic supranuclear ophthalmoplegia, and a resting tremor of her right hand. bilateral ptosis and marked temporal muscle wasting. Her sensory examination found loss of pinprick sensation, temperature and vibration bilaterally up to her hips. She had bilateral vibration loss at her fingertips. She had loss of proprioception at her toes. She had bilateral dysdiadochokinesia with significant ataxia on finger to nose testing. Arreflexic in her lower extremities. On cognitive testing she was found to have moderate dementia with significant deficits in registration and construction as well as ideomotor apraxia. | | - | movement disorder (ataxia) | |
