Brief Summary:
This study will determine the effectiveness of a drug, dimethoxbenzylidene anabaseine, in producing beneficial effects similar to that of nicotine in individuals with schizophrenia.
Detailed Description:
Schizophrenia is a chronic and severe brain disorder that can significantly impact quality of life. It is characterized by delusions, paranoia, and disordered thinking. The cause of schizophrenia has not yet been determined. However, there are many treatments, including drug therapy and cognitive behavioral therapy, that may help to alleviate symptoms of the condition. Nicotinic receptors are involved in a number of biological processes; they are numerous throughout the central and peripheral nervous systems and are diverse in structure and expression. Genetic and neurobiological research has identified decreased expression of the a7 nicotinic receptor as an element in schizophrenia that is related to poor psychosocial outcome. Data indicate that drug therapy may reduce this deficit in receptor expression. Nicotine has been found to stimulate the a7 nicotinic receptor; however, the physiological dependence associated with nicotine makes it an undesirable option. Dimethoxbenzylidene anabaseine (DMXB-A) can stimulate the a7 nicotinic receptor; its advantages include easy oral administration and the lack of dependence-causing effects. This study will determine whether DMXB-A can safely and effectively stimulate the a7 nicotinic receptor in schizophrenia patients and reduce their neurobiological symptoms.
This study will last 6 weeks. Participants will have study visits each week for the duration of the study. During each visit, participants will be randomly assigned to receive either DMXB-A or placebo. An electrocardiogram (EKG) will measure the heart function of participants and participants' blood pressure will be measured. After the first dose of either DMXB-A or placebo, participants will receive a second dose 2 hours later. An evoked potential test, which measures the brain's response to stimuli, will be performed after both doses. Neuropsychological tests, such as verbal reasoning and visual retention, will be performed following the second dose of either DMXB-A or placebo.
