OBJECTIVE: Patients with schizophrenia have a higher prevalence of metabolic syndrome (MetS) than the general population. Minimizing weight gain and metabolic abnormalities in a population with an already high prevalence of obesity is of clinical and social importance. This randomized controlled trial investigated the effect of monthly nutritional education on weight change and metabolic abnormalities among patients with schizophrenia in Japan. METHODS: From July 2014 to December 2014, we recruited 265 obese patients who had a DSM-IV diagnosis of schizophrenia or schizoaffective disorder...

There is growing interest about the potential of diet and nutrients to improve the mental health of the population and for the treatment of psychiatric disorders. In the case of schizophrenia, the limitations of antipsychotic drugs to achieve adequate rates of clinical remission and functional recovery have promoted the search for complementary approaches. This narrative review approaches the dietary patterns and interventions in schizophrenia, efficacy of specific nutrients and therapeutic modulation of the gut microflora by probiotics...

Inappropriate dietary intake and poor nutritional status are reported to be associated with metabolic syndrome and psychopathology in patients with schizophrenia. We hypothesized that inappropriate dietary habits and insufficient dietary intake of specific nutrients are associated with schizophrenia. To test the hypothesis, we assessed the dietary habits and nutritional intake of patients with schizophrenia and then developed suitable dietary guidelines. In total, 140 subjects (73 controls and 67 patients with schizophrenia from community mental health centers) were included, and dietary intakes were analyzed using a semi-quantitative food frequency questionnaire...

Mental illness, including depression, anxiety and bipolar disorder, accounts for a significant proportion of global disability and poses a substantial social, economic and heath burden. Treatment is presently dominated by pharmacotherapy, such as antidepressants, and psychotherapy, such as cognitive behavioural therapy; however, such treatments avert less than half of the disease burden, suggesting that additional strategies are needed to prevent and treat mental disorders. There are now consistent mechanistic, observational and interventional data to suggest diet quality may be a modifiable risk factor for mental illness...

OBJECTIVE: Second-generation antipsychotics increase the risk of diabetes and other metabolic conditions among individuals with schizophrenia. Although metabolic testing is recommended to reduce this risk, low testing rates have prompted concerns about negative health consequences and downstream medical costs. This study simulated the effect of increasing metabolic testing rates on ten-year prevalence rates of prediabetes and diabetes (diabetes conditions) and their associated health care costs...

Kynurenine metabolites are generated by tryptophan catabolism and regulate biological processes that include host-microbiome signaling, immune cell response, and neuronal excitability. Enzymes of the kynurenine pathway are expressed in different tissues and cell types throughout the body and are regulated by cues, including nutritional and inflammatory signals. As a consequence of this systemic metabolic integration, peripheral inflammation can contribute to accumulation of kynurenine in the brain, which has been associated with depression and schizophrenia...

DiGeorge/22q11.2 Deletion Syndrome (22q11DS) is a common genetic microdeletion syndrome that underlies several neurodevelopmental disorders including autism, attention deficit/hyperactivity disorder, and schizophrenia. In addition to cognitive impairments, those with 22q11DS have disrupted feeding and swallowing from birth onward. This perinatal dysphagia significantly compromises nutritional status, impairs appropriate weight gain, and can lead to life threatening aspiration-based infections. Appropriately timed excitation and inhibition of brainstem hypoglossal motor neurons, which innervate tongue muscles, is essential for proper feeding and swallowing...

OBJECTIVE: Psychotic disorders in childhood and early adolescence often progress to chronic schizophrenia, but in many cases there are diagnosable medical and genetic causes or risk factors. We reviewed our clinical experience and the relevant literature to identify these factors and to define their clinical features, appropriate work-up and treatment. METHOD: We reviewed the results of comprehensive medical evaluations of 160 psychotic children and adolescents in our center...

Studies have shown that schizophrenic patients seem to have nutritional deficiencies. Ascorbic acid (AA) has an important antioxidant effect and neuromodulatory properties. The aim of this study was to evaluate the effects of AA on locomotor activity and the acetylcholinesterase activity (AChE) in an animal model of schizophrenia (SZ). Rats were supplemented with AA (0.1, 1, or 10 mg/kg), or water for 14 days (gavage). Between the 9th and 15th days, the animals received Ketamine (Ket) (25 mg/kg) or saline (i...

Protein-energy wasting is associated with poor outcome in various clinical settings. However, the prevalence of malnutrition and the prognostic impact of nutritional status are poorly understood in institutionalized patients with chronic schizophrenia. This study aimed to assess the predictive ability of the Geriatric Nutritional Risk Index and Onodera's Prognostic Nutritional Index for long-term outcomes in patients with chronic schizophrenia. All measurements, including nutritional scores, were performed at baseline after the enrollment of 542 (64...

People experiencing a severe mental illness (SMI), such as schizophrenia, schizoaffective disorder, bipolar affective disorder or depression with psychotic features, have a 20-year mortality gap compared to the general population. This 'scandal of premature mortality' is primarily driven by preventable cardiometabolic disease, and recent research suggests that the mortality gap is widening. Multidisciplinary mental health teams often include psychiatrists, clinical psychologists, specialist mental health nurses, social workers and occupational therapists, offering a range of pharmacological and nonpharmacological treatments to enhance the recovery of clients who have experienced, or are experiencing a SMI...

The etiology and pathophysiology of schizophrenia (SCZ) remain obscure. This study explored the associations between SCZ risk and serum levels of 39 macro and trace elements (MTE). A 1:1 matched case-control study was conducted among 114 schizophrenia patients and 114 healthy controls matched by age, sex and region. Blood samples were collected to determine the concentrations of 39 MTE by ICP-AES and ICP-MS. Both supervised learning methods and classical statistical testing were used to uncover the difference of MTE levels between cases and controls...

Epidemiological studies have shown that periods of poor nutrition during pregnancy can lead to an increased risk of metabolic and psychiatric disorders in the offspring. In addition, some individuals with disorders such as schizophrenia show signs of impaired insulin signalling. These findings indicate that there may be a link between metabolism and neuronal function and they also provide supporting evidence for neurodevelopmental origins of mental illness. This chapter gives a detailed protocol for generation of the maternal low-protein (LP) rat model, which leads to metabolic disturbances in the offspring...

Docosahexaenoic acid (DHA), a polyunsaturated fatty acid (PUFA) enriched in phospholipids in the brain and retina, is known to play multi-functional roles in brain health and diseases. While arachidonic acid (AA) is released from membrane phospholipids by cytosolic phospholipase A2 (cPLA2), DHA is linked to action of the Ca(2+)-independent iPLA2. DHA undergoes enzymatic conversion by 15-lipoxygenase (Alox 15) to form oxylipins including resolvins and neuroprotectins, which are powerful lipid mediators. DHA can also undergo non-enzymatic conversion by reacting with oxygen free radicals (ROS), which cause the production of 4-hydoxyhexenal (4-HHE), an aldehyde derivative which can form adducts with DNA, proteins and lipids...
