Filter by:In the last decade several evidences show that cognitive impairment is a major feature of bipolar disorder (BD), that is strongly associated with patients' functional outcome. The most affected cognitive domains in BD are attention, memory and executive functions. BD represents a mental illness of considerable therapeutic complexity and the fight against cognitive and functional deterioration have contributed to increase the interest in the development of specific therapeutic strategies.There is the need of new non-pharmacological interventions in BD in order to improve not only affective symptoms, but also cognitive dysfunctions, with the final goal to achieve full functional recovery. The present study is focused on Functional Remediation (FR), a novel group intervention created by the Bipolar Disorder Unit of the Hospital Clinic of Barcelona and designed specifically for bipolar patients, based on a neuro-cognitive-behavioural approach. It involves neurocognitive and psychoeducation techniques (21 weekly sessions). The present study aims to assess FR efficacy in improving cognitive deficits and psychosocial functioning in a sample of euthymic patients with BD, compared to standard treatment (TAU). This is a randomized and rater-blind trial, involving 54 adult out-patients diagnosed with BD I or II (DSM-5 criteria) and clinically stable for at least two months. Patients will be assessed at baseline, post-treatment and 6-months follow-up, on validated cognitive, clinical and functional rating scales. The main result expected is that patients receiving FR will show better cognitive and psychosocial performance, further confirming the preliminary evidence on the utility of FR as an element of standard care for BD patients.
Patients with bipolar disorders report an acceleration or slowing of time flow, and patients with schizophrenic spectrum disorders a time fragmentation. These disorders would be linked to disorders of the sense of self. Assessing these time-related disorders could help to better predict psychotic conversion in vulnerable subjects. In this protocol, the investigators wish to develop playful methods for the evaluation of alterations in the passage of time, based on the use of virtual reality. The protocol will be tested in stabilized but chronic bipolar or schizophrenic patients, vs. healthy subjects matched on age, sex, and study level. The protocol will include two experimental sessions. It will begin with a waiting room-like session, at the end of which the subject will be asked to retrospectively estimate the time that will have passed. The games that will follow will all be based on the principle of temporal waiting. A first signal will indicate the start of the trial, and a target will be presented at varying times after this first signal. The later the target is presented, the more the subject expects and prepare for the target, and the faster he or she is. This time delay is measured by the subject's response (response time, error rate, eye fixation), but also by electrical signals measured by electroencephalography (EEG). The two experimental sessions will include several temporal manipulations during these tasks, intended to highlight alterations in the time flow in patients compared to controls. In one of the sessions, a starfield will be presented and the speed of the stars in the starfield will be manipulated, as a proxy for the speed of the environment. In one condition, the speed of the object will be average, and in the other the speed will be self-adjusted by the subject. In a control condition, the speed of the object will be zero. In the other experimental session, distractors will be presented during the waiting phase of the target. They will be presented either simultaneously or asynchronously. In one control condition the distractors will be absent. In both sessions it will be examined how the behavioral and EEG cues are affected by the manipulations. A double dissociation is expected, with greater disturbance in patients with bipolar disorder when standard movement is used, whereas patients with schizophrenia should be disturbed mainly when asynchronous distractors are presented.
This study will determine the effectiveness and safety of S-Ketamine in depression patients undergoing electroconvulsive therapy.
The objective of this study is to determine whether the practice of a non-drug related intervention technique (behavioral modification technique consisting of a combination of breathing exercises, cold exposure and meditation) has an effect on long-term cannabinoid receptor function in a control group as well as in a group of patients suffering from bipolar affective disorder (BAD). Specifically, the objective of this study is to test whether the applied behavioral modification technique is able to alter cannabinoid receptor density in brain areas that modulate mood and motivational drive (such as vmPFC, PAG, VTA, amygdala and OFC). The investigators believe that these studies will form the impetus for a better understanding and deployment of non-drug related treatment methods in patients with various depressive symptoms. In particular, it appears that the proposed behavioral modification technique might be a powerful, currently under-appreciated, method to positively modulate the brain's own cannabinoid system.
Phase 3 safety and efficacy study of Staccato Loxapine in the treatment of acute agitation in schizophrenic or bipolar disorder patients.
This study is a pilot RCT to evaluate the effectiveness and implementation challenges of an intervention using volunteer 'Health Champions' matched with service users to support service their physical health goals.
Assessment of cognitive function in manic bipolar patient
For more severe and treatment-resistant cases in schizophrenia and bipolar disorder, electroconvulsive therapy (ECT) is often very effective. The purpose of this study is to investigate the brain structure and function changes after ECT treatment. The neuroimaging marker which may predict the outcome of ECT is also studied in this research.
This study will investigate the effects of aerobic exercise on mental states, cognition, BDNF, and long-term outcomes in patients with bipolar disorder.
Bipolar disorders are common psychiatric disorders characterized by severe and recurrent symptomatic periods (Major Depressive Episode, mania, hypomania) and interictal periods characterized by persistent residual symptoms, impaired functioning and quality of life. In addition, the prognosis of bipolar disorder is aggravated by an increased risk of suicide and a high frequency of somatic comorbidities. Poor adherence is one of the major factors influencing the course of the disorder and one of the causes of ineffective treatments. Considering that between 20 and 60% of patients with bipolar disorder have problems with adherence. Adherence is modulated by a number of socio-demographic, clinical and neuropsychological factors. It is also modulated by the knowledge, beliefs and In addition, studies have shown that the reasons attributed to poor adherence are different depending on whether questioning patients or healthcare professionals. This fault diagnosis, assessment of the causes and "fit" into the reasons associated with poor adherence is an aggravating factor of the problem. However, this factor seems modifiable by better training of professionals. A team from Newcastle University in England has developed a training program for all health professionals to improve the diagnosis and understanding of compliance issues in bipolar patients and provide simple tools to fight against patients with this problem. The investigators assume that this training will improve medication adherence among outpatients by trained professionals.
