14 results about "Negative symptom" patented technology

A method is provided to bring about the necessary improvement in the user's empirical negative symptoms of schizophrenia. The calculation system can obtain a first metric associated with the user from multiple point in time. The calculation system can repeat the operation of identifying a configuration file selected based on the endpoint for improving empirical negative symptoms from multiple point in time. The calculation system can repeatedly present a set of content items identified by the configuration file to encourage the user to perform activities toward achieving the endpoint. The calculation system can obtain a second metric associated with the user from multiple point in time. If the second metric is lower than the first metric, the user is considered to have improved in the empirical negative symptoms of schizophrenia. The calculation system can enhance the effectiveness of medications the user is taking to cope with schizophrenia.

The present invention relates to novel compounds of Formula (I'), wherein P, Q, A, B, m, n, R1, R2, R9, R10, R11 and R12 are defined as in Formula (I'). These compounds may be useful as muscarinic M4 receptor subtype ("M4-mAChR") positive allosteric modulators which are useful for the treatment or prevention of neurological and psychiatric disorders associated with muscarinic M4 receptor dysfunction and diseases in which the M4 receptor is involved. The invention is also directed to pharmaceutical compositions comprising such compounds, to processes of preparing such compounds and such compositions, and to the use of such compounds for the prevention or treatment of neurological and psychiatric disorders and diseases such as for example, cognitive decline, both positive and negative symptoms in schizophrenia as well as other disorders modulated by M4 muscarinic receptors.

The present invention relates to a compound for use in the treatment of schizophrenia, also known as CF3CN and referred to herein as the compound of formula I, 4-(6-oxo-2-(trifluoromethyl)-3,6-dihydrochromeno[7,8-d]imidazole-8-yl)benzonitrile. Preferably, the treatment of schizophrenia is the treatment of one or more symptom categories of schizophrenia. More preferably, the treatment is for the negative symptoms of schizophrenia. Alternatively, the treatment is for the cognitive symptoms of schizophrenia.

This invention discloses the application of catalpol in the preparation of drugs for the prevention and treatment of schizophrenia and the alleviation of the glucose and lipid metabolism side effects of olanzapine. Using a schizophrenia model mouse model induced by the commonly used MK801, the therapeutic effect of catalpol on schizophrenia was investigated, and the therapeutic effect of catalpol on the glucose and lipid metabolism side effects of the commonly used drug olanzapine was investigated through long-term gavage administration. A systematic study of catalpol was conducted from pharmacodynamic, behavioral, and morphological perspectives. The results showed that catalpol effectively improved the behavioral characteristics of the schizophrenia model mice, alleviated negative symptoms and cognitive impairment; catalpol effectively improved olanzapine-induced obesity and lipid metabolism disorders. This provides a theoretical research basis for the development of catalpol into a drug for the treatment of schizophrenia.

The invention relates to a novel compound as a 5-HT2A receptor inverse agonist, and a preparation method and a pharmaceutical composition thereof. The invention also relates to application of the compound or the pharmaceutical composition in preparation of drugs for treating 5-HT2A receptor related diseases, wherein the diseases comprise non-motor symptoms caused by Parkinson's disease, such as delusional disorder, hallusion, depression, anxiety, cognitive disorder and sleep disorder; dementia-related mental disorders; major depression; or negative symptoms of schizophrenia and the like.

This invention relates to the use of mGluR5 positive allosteric modulators in the treatment of a psychiatric condition in which depressive symptoms are prominent, including major depressive disorder, bipolar disorder, post-traumatic stress disorder, substance use disorder, depression-related aspects of schizophrenia (e.g. negative symptoms and cognitive impairment associated with schizophrenia), obsessive compulsive disorder, an eating disorder, autism spectrum disorder, chemotherapy-related cognitive dysfunction, Parkinson's disease, multiple sclerosis, clinical high risk for psychosis, and attenuated psychosis syndrome in select patients who, for instance, have objectively determined cognitive impairment or poor cognition (such as objectively determined impaired learning and / or memory) and / or certain EEG characteristics.

This description relates to gastro-resistant controlled-release dosage forms comprising Compound (I): (see Formula) (I), or a pharmaceutically acceptable salt and / or solvate thereof, the pharmacokinetic properties of these dosage forms, and their preparation. The novel dosage forms described herein are useful for reducing the risk of QT prolongation in a subject and for treating a disorder in a subject in need, e.g., a subject diagnosed with schizophrenia, for example, in the treatment of negative symptoms in a subject diagnosed with schizophrenia who has the CYP2D6 EM genotype.
