Case Report in the Brazilian Context: Cognitive and Behavioral Changes Following an Electric Injury

Electrical injury (EI) is the sequel of an electrical shock. Physical sequelae are most common, but also other symptoms can happen, such as neurological symptoms, psychiatric alteration, and cognitive decline. The repercussion of EI can happen whether or not the head is a point of contact with the electrical current. There are no official diagnostic criteria for cognitive repercussions of EI, which may lead to incorrect diagnostics and confusion with other most frequent causes of dementia, such as frontotemporal dementia, pseudodementia, or dementias for reversible causes. In this case report, we described a right-handed man, aged 56 years old, referred to our service due to behavioral changes and cognitive alterations related to electric shock. The psychiatric team has monitored him, but cognitive deficits have raised doubts about the presence of dementia syndrome. The neuropsychological evaluation revealed severe deficits and loss of functionality, which filled the criteria for major neurocognitive disorder according to the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5). Adding these findings to the patient's history and after a detailed investigation of other causes of dementia, we concluded that this is a possible case of EI with strong neuropsychological symptoms. This case report should help clinicians to recognize this condition and its features. We aimed to share the importance of recognizing the neuropsychological and psychiatric features of EI, mainly in the Brazilian context
