“…These are isolated cases of manic symptoms; behavioral disorders including hyperactivity, inattention, easy distractibility, inattention, over-talkativeness, poor academic performance, forgetfulness in daily activities, irritability, stubbornness, emotional lability, and temper tantrums; manic symptoms; and cognitive issues. 3 4 5 6 7 8 Psychotic symptom description in context to MMD is scarce. Klasen et al reported the presentation of a 12-year-old boy who presented with acute-onset verbosity, persecutor beliefs, and auditory hallucinations, with no physical or neurological abnormalities.…”

“…He responded to antipsychotics which were continued for 3 months, and the boy was having normal functioning till 1-year follow-up. 6 The second case describes a 23-year-old male with diagnosis of schizophrenia having multiple episodes and increased susceptibility to develop extrapyramidal symptoms with antipsychotics. No apparent neurological deficit was observed; however, he revealed significant difficulties on high-level attention, reasoning, and problem-solving tasks on neuropsychological assessment.…”

“…5 Considering psychotic symptoms with MMD, a case of acute transient psychosis and another with predominant delusion, hallucination, fatuous affect, and occasional disinhibited behavior with marked sensitivity to extrapyramidal symptoms have been described. 6 7 We here present a case with delusion of persecution and agnosia and apraxia without any sensorimotor symptoms, which lead to a substantial delay in diagnosis and prompted detailed evaluation.…”

Moyamoya disease (MMD) is a rare arteriopathy associated with cerebral ischemia, due to stenosis or occlusion of the internal carotid artery and its branches and primarily presenting with stroke. However, neuropsychiatric symptoms such as acute psychosis, manic symptoms, attention deficits, and behavioral problems are reported in relation to MMD. We describe here a case of an adult female, who presented with headache, easy irritability, and suspiciousness against family members, inability to identify familiar objects and faces, and inability to perform activities easily done earlier. This case appears informative as the presence and excessive importance given to behavioral symptoms lead to substantial delay in her diagnosis.

“…The rates of hemorrhage reported in several large studies are presented in Table 4. In individual moyamoya patients, neurological symptoms secondary to moyamoya included laryngomalacia [118], hypotension encephalopathy [117], behavioral changes [119], oral and written language deficits [119,128], transient psychosis [121,129,173], hemiplegia [126,131], hearing loss [132], and cognitive difficulties [120]. Movement disorders as symptoms of moyamoya included chorea [122,123], dystonia [124,125], hemifacial spasms [130], and hemiballismus [127].…”

Moyamoya, a rare angiographic finding, is characterized by chronic and progressive stenosis at the terminal end of the internal carotid artery, followed by collateralization of the cerebral vasculature at the base of the skull. Coined by Suzuki and Takaku in 1969, the term “moyamoya” means a “puff of smoke” in Japanese, a reference to the angiographic appearance of moyamoya collateralization. Moyamoya is most commonly found in East Asian countries, where much governmental and civilian effort has been expended to characterize this unique disease process. However, despite its rarity, the occurrence of moyamoya in Western countries is associated with significant divergence regarding incidence, gender, sex, age at diagnosis, clinical presentation, and outcomes. Here, we attempted to review the Western literature on moyamoya presentation using the PubMed database to characterize the Western phenotype of moyamoya. We were guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR). We reviewed papers generated from a search with keywords “moyamoya case report,” those reported from a Western institution, and those reported on a relevant association. Our scoping review demonstrated various clinical associations with moyamoya. Moreover, we summarized the demographic profile and clinical symptomatology, as well as reported disease associations to better elucidate the Western phenotype of moyamoya.

“…Psychiatric manifestations associated with MMD in children are uncommon. [ 4 ] These include schizophrenia,[ 4 ] acute transient psychosis,[ 5 ] and mania. [ 6 ] Some patients of MMD also show cognitive impairment, learning disability, and attention deficits.…”
