He had been well 8 months previously. At that point, the family noted the onset of apathy and problems with sleep. Two months later, the patient was noted to have problems with balance and gait, and had a number of unprovoked falls with gait unsteadiness and “dizziness.” He then developed jerky movements, especially in the arms. In the ensuing months, he had worsening disorientation and cognitive decline. He started having difficulties with recognizing relatives. He became withdrawn, akinetic, and mute. He was conscious, but did not have any meaningful reactions to voice commands.
