Suicide risk is thought to increase with a greater potential for activation of suicide-related schemas. Suicide schemas are less likely to be activated with reductions of emotional range associated with certain negative symptoms of schizophrenia. The study tested whether suicide risk would increase in patients with recent onset schizophrenia with increased potential for suicide schema activatio...

Diminished expression is a diagnostic feature of a range of schizophrenia-spectrum disorders/conditions and is often unresponsive to treatment, is present across premorbid, first episode and various clinical states, and is considered a poor prognostic indicator. Surprisingly, little is known about diminished expression. The present study sought to address this issue by evaluating a commercially...

Blunted affect, also referred to as emotional blunting, is a prominent symptom of schizophrenia. Patients with blunted affect have difficulty in expressing their emotions. The work of Abrams and Taylor and their development of the Rating Scale for Emotional Blunting in the late 1970's was an early indicator that blunted affect could indeed be assessed reliably. Since then, several new instrumen...

Apathy, defined as a reduction in voluntary goal-directed behaviors, is one of the most common behavioral symptoms encountered in Alzheimer disease (AD). However, the processes underlying the different components of apathy are still unclear. The aim of this study was to explore a particularly important aspect of executive function in daily life: multitasking [assessed with the Modified Six Elem...

BACKGROUND In order to improve the treatment of medication-resistant negative symptoms in schizophrenia, new interventions are needed. Neuropsychological considerations and older reports in the literature point towards a potential benefit of body-oriented psychological therapy (BPT). This is the first randomized controlled trial specifically designed to test the effectiveness of manualized BPT ...

OBJECTIVE To evaluate dextromethorphan combined with ultra low-dose quinidine (DMq) for treating pseudobulbar affect (PBA) in patients with amyotrophic lateral sclerosis (ALS) or multiple sclerosis (MS). METHODS In a 12-week randomized, double-blind trial, ALS and MS patients with clinically significant PBA (a baseline score ≥13 on the Center for Neurologic Studies-Lability Scale [CNS-LS]) we...

Psychopathology, treatment response, and remission rates were evaluated (based on the Positive and Negative Syndrome Scale (PANSS), severity of symptoms only). On admission, the most frequently observed symptoms were lack ...

OBJECTIVE Research on clinical reasoning has been useful in developing expert systems. These tools are based on Artificial Intelligence techniques which assist the physician in the diagnosis of complex diseases. The development of these systems is based on a cognitive model extracted through the identification of the clinical reasoning patterns applied by experts within the clinical decision-ma...
