Case Reports
[A case of Usher's syndrome associated with psychotic symptoms: diagnosis and follow-up in a psychiatric unit].
Usher's syndrome is a heterogeneous autosomal recessive disorder characterised by dual sensory impairment: profound congenital hearing impairment and progressive visual loss due to retinitis pigmentosa, sometimes associated with vestibular dysfunction. Some patients develop a psychotic illness, the etiology of which is still debated. Diagnosis may be difficult, and there are only a few reports in the psychiatric literature. ⋯ Access to mental health services is particularly difficult for deaf and deaf-blind people, and difficulties in communication are a challenge for patients and for caregivers too. Antipsychotic medications are helpful for associated psychotic symptoms. Potential link between Usher syndrome and psychosis is still unclear and needs further studies.

In our daily practice in public hospitals, we are regularly confronted with the paradox of helping patients, who do not ask for help. Although the French law is clearly defined to allow us to treat patients suffering from psychiatric conditions, who are unable to give their consent, it is not the case for those with addictive disorders. In fact, their disorder does not always (or does not yet) justify treatment without their consent, according to the 1990 law (psychiatric treatment without the patient's consent). ⋯ Pathology begins when an individual can no longer choose what he/she needs to do. We do not consider that a brief-concrete approach is better than any other approach, but its pragmatic nature seems to fit in with the new conception of addiction therapy, with earlier intervention. However, is it possible to make changes outside of a crisis situation? We are unable to answer this question, except to say that the best time for change is that chosen by the patient.

Attention-deficit hyperactivity disorder (ADHD) is a common and impairing neuropsychiatric disorder with preschool onset. ADHD occurs in approximately 3-9% of the childhood population. There is a much higher incidence rate in boys who are around three times more likely than girls to be diagnosed. Approximately 30-60% of individuals diagnosed with ADHD in youth have symptoms that persist into adulthood. ⋯ This review provides an overview of the main imaging studies that investigated the neurobiological substrate of ADHD. Some guidelines for future functional magnetic imaging studies are also suggested.

Over the last 30 years, several questionnaires have been developed and validated in order to assess many aspects of the motivation to eat that might be susceptible to impair adequate food intake and body weight control. A few of such questionnaires are described here, in particular, the "Three Factor Eating Questionnaire" also called the "Eating Inventory", and the "Dutch Eating Behavior Questionnaire". Critical aspects of the motivation to eat assessed by these tools are presented, such as dietary restraint, disinhibition, hunger, vulnerability to eat in response to external cues or emotional states, etc. ⋯ It then becomes critical to know whether the psychological dimensions assessed by such questionnaires reflect the action of pharmacological agents that induce weight gain. A research project is now in progress at Sainte-Anne Hospital to investigate many dimensions of the motivation to eat, as assessed by the questionnaires, in psychiatric patients receiving various types of antipsychotic agents. The results of this original study might provide hints about the mechanisms that lead to body weight gain in patients receiving certain types of antipsychotic pharmacological agents and potentially help in preventing or reversing the weight gain associated with such treatments.
