Introduction Since Kraepelin and Bleuler, schizotypy was understood as a mild expression of psychosis, a latent form with the same trajectory but different severity. They pointed characteristics such as being eccentric, unreasonable, supersticious or hipersensitive, interpersonal aversiveness (often related to suspiciousness and expectation of rejection), ambivalence, anhedonia,… and psychosis-like features that don’t usually lead to help-seeking. Objectives To do a case review Methods We report a case of a 17 years old boy with a childhood trauma history who started psychiatric consultations a year and a half ago because his “usual” (as his mother referred) strange behaviour got worse, which was perceived by his ENT specialist. During the appointments, the patient showed suspiciousness, odd speech, inappropriate affect, tendency to social withdrawal, obsessive ruminations with sexual content and occasional perceptual experiences (such as depersonalization, derealization and auditory hallucinations). Results Psychosis and schizotypy are linked historically and phenomenologically, which is evidenced by their placement in non-affective psychosis in the ICD-10 and DSM-5, and it is known that the direct observation (by clinicians or family members) during the childhood and adolescence are key for a correct diagnosis. In fact, this construct reflects a phenotypic expression of vulnerability to schizophrenia, and during childhood or adolescence it may be understood as an early mental risk state. Conclusions In contrast to models of psychosis that mainly rely on positive features and assume a progression of them, the positive traits of schizotypy seem to be beneficial and related to a “benign or happy schizotypy” according to the articles we reviewed.

Introduction It’s well known the challenge of differential diagnosis between Obssesive compulsive disorder and autism since their symptoms (intrusive, recurrent thoughts and repetitive behaviours) often overlap. Objectives We report a case of a 14 years old boy diagnosed of ASD who was hospitalized for the first time due to difficult management of repetitive behaviours that made him incapable of doing basic activities without help. To interrupt them led to anxiety, aggressive responses and to insistence on sameness behaviours. Only with this information and with the literature research we made, anyone could tell the problem was probably an ASD symptom. However, during his evolution it was difficult to know whether this behaviour was due to ASD or OCD: after adjusting the medication, and when he started trusting his therapists, he told us about a theory he believed so he could explain the uncomfortable ideas that crossed his mind more than often, so he used those behaviours as an anxiety-reduction technique. This new situation was the fuel to make the present review. Methods To report a case. Results The results are included in the “conclusions” section. Conclusions Although there is an ongoing debate concerning the nature of the symptoms in ASD versus those observed in OCD, there are commonly used criteria to differentiate them according to the articles we reviewed: Disclosure No significant relationships.
