He is concerned that she has had abnormal behavior and involuntary movements of her body for the last 3 weeks. She now has difficulty remembering names, dates, and events. She even fails to recognize pictures of her children. She was in her normal state of health 3 weeks ago. There is no history of fever, headache, head trauma, drug abuse, or change in medications. Past medical history is significant for type 2 diabetes mellitus. She takes metformin and a multivitamin. Family history is negative for psychiatric illness. Her blood pressure is 13487 mm Hg, the heart rate is 70min, and the temperature is 37.1C 98.8F. The exam is occasionally disrupted by sudden episodic jerking of her limbs. She is drowsy but arousable to voice, and is disoriented and confused. Extraocular movements are normal. Cranial nerves are intact. There is no neck stiffness. Her laboratory results are significant for:Hemoglobin 14.3 gdLWhite blood cells 6,900mm3Platelets 347,000mm3Creatinine 1.0 mgdLSodium 146 mmolLPotassium 4.1 mEqLCalcium 9.1 mgdLGlucose random 132 mgdLTSH 2.5 mULShe is admitted to the neurology service. A head MRI, lumbar puncture, and EEG are performed. The MRI is nondiagnostic. Electroencephalography EEG reveals periodic spike and slow waves at an interval of 1 second. Cerebrospinal fluid is positive for protein 14-3-3. What is the most likely diagnosis?? A: Acute disseminated encephalomyelitis, B: Autoimmune encephalitis, C: Creutzfeldt-Jakob disease, D: Hashimoto thyroiditis, E: Herpes viral encephalitis,  <response>: This is a clinical case scenario describing a 60-year-old woman with recent onset of abnormal behavior, involuntary movements, memory impairment, and confusion. Key findings include:- Subacute onset over 3 weeks- Cognitive decline - failing to recognize family members- Myoclonus involuntary jerking of limbs - EEG showing periodic spikes and slow waves- CSF positive for 14-3-3 proteinBased on the subacute progression, rapid cognitive decline, myoclonus, characteristic EEG, and positive 14-3-3 protein in CSF, this presentation is most consistent with Creutzfeldt-Jakob disease CJD. CJD is a rapidly progressive neurodegenerative prion disease characterized by dementia, myoclonus, and characteristic EEG findings. The positive 14-3-3 protein in CSF supports the diagnosis. The other choices do not fit with the clinical presentation.C: Creutzfeldt-Jakob disease
