Psychiatrymiddle twist
A 17-year-old is brought to the general practitioner by his father, whose own brother has schizophrenia. Over eight months the boy's grades have fallen, he has given up football and he spends most of the day in his room. Three months ago he told his father over four days that his phone was broadcasting his thoughts, then stopped mentioning it and has not raised it since; he now calls that period a weird patch. He uses no substances and urine toxicology is negative. He is not suicidal, and examination and blood tests are normal. Which one of the following is the most appropriate management?
