Óxido Nitroso/efeitos adversos, Psicoses Induzidas por SubstânciasResumo
O consumo recreativo de óxido nítrico (N2O) tem aumentado de forma preocupante. Apesar da sua toxicidade hematológica/neurológica estar bem documentada, os efeitos psiquiátricos permanecem subvalorizados. A exposição crónica ou em altas doses pode causar défice de vitamina B12, potenciando estas manifestações. Apresentamos o caso de um homem de 27 anos, com consumo recente de N2O, internado por primeiro episódio psicótico. Os exames laboratoriais revelaram défice de vitamina B12 e ácido fólico. O tratamento com antipsicótico e suplementação possibilitou a completa remissão de sintomas. A determinação de um diagnóstico formal aquando de um primeiro episódio psicótico constitui um desafio clínico. Este caso evidencia o potencial do N2O para desencadear quadros psicóticos, sobretudo em indivíduos vulneráveis. Face ao aumento do consumo recreativo, é essencial definir estratégias de saúde pública e promover a formação dos clínicos para diagnóstico precoce e intervenção eficaz.
