Case 2:
A 75-year-old woman, who is a homemaker and has completed 12 years of schooling, was referred to the neuropsychiatric clinic because she has been experiencing memory loss for events and often asked the same questions since 1.5 years ago. She had profound sadness and frequently cried over the previous year after the passing of her spouse. The presence of RBD was detected. In the past one year ago, she has been experiencing intense visual hallucinations. For example, she sometimes perceives the presence of two children in her home and engages in conversations with them. Once, she had an unusual visual hallucination known as an after-image, referred explicitly to as Palinopsia. She saw a canine on the road, and after three hours, she reencountered it while traversing a different street, ten kilometers further. Previous medical history encompasses ischemic heart disease, hypertension, and a record of thyroid surgery. Currently, a psychiatrist has recommended a daily dosage of 200mg of Pregabalin, 25mg of Nortriptyline, and Ginkgo biloba.
The neurological examination indicated the presence of stiffness on the left side, slowness of movement in the upper limbs, and slight resting tremor. The overall MoCA score was 15, with an additional point for 12 years of schooling. The sub-scores were as follows: visuospatial/executive function 1 out of 5, Naming 2 out of 3, Attention 3 out of 6, Language 1 out of 3, Abstraction 1 out of 2, Recall 0 out of 5 (MIS= 6 out of 15), and Orientation 6 out of 6.
