Active clinical trials for "Memory Disorders"

The purpose of this study is to test the effects of tDCS (Transcranial Direct Current Stimulation) on stroke patients with working memory problems.

This study will evaluate whether Atomoxetine improves cognition in healthy volunteers as well as patients with schizophrenia. Atomoxetine is a drug that has been Food and Drug Administration (FDA) approved for Attention Deficit Disorder and allegedly increase the amount of the neurotransmitter dopamine in the frontal cortex of the brain.

The primary purpose is to determine if patients scheduled to receive prescription corticosteroid therapy for inflammatory illnesses who are given either memantine or riluzole pretreatment will show lesser declarative memory impairment than those receiving placebo. The exploratory purpose is to determine if patients scheduled to receive prescription corticosteroid therapy for inflammatory illnesses who are given memantine or riluzole pretreatment will show a smaller increase in manic/hypomanic symptom severity than those receiving placebo.

Providing a combination of synergistic dietary supplements, such as vitamins B6, B12, and folate, as well as curcumin, lemon balm, and American ginseng is hypothesized to promote brain health and aid with brain fog, mental clarity, ability to handle stress, mood, focus, and productivity, as well as promote overall well-being.

The study aim is to determine if periodic online cognitive exercises (Lumosity) improve memory function in ruptured cerebral aneurysm patients with disabling baseline memory deficits within the first 24 months after rupture. Half of the subjects will be randomized to use Lumosity-designed online cognitive exercises and half will serve as an active control group performing online crossword puzzles.

This study will compare smartphone usage data between three groups of patients diagnosed with either a memory complaint, mild cognitive decline, or Alzheimer's disease.

Behavioral interventions currently provide the most useful approach to addressing the behavioral and social needs of those with Mild Cognitive Impairment (MCI) due to Alzheimer's or other diseases. This randomized, multisite, 3-arm study will investigate the impact of computerized brain fitness vs yoga vs an active control group (wellness education) on changes in cognitive function, daily functioning and quality of life in persons with Mild Cognitive Impairment (MCI) and their partner. In addition, in vivo neuroimaging measures of plasticity during the pre- and post-intervention periods will be measured and compared between the three different treatment groups. These neuroimaging measures of plasticity will be investigated in their relationship to the cognitive outcomes within each group.

When people are tested on a previously learned material, they will later remember it better even when compared to a condition where they can re-study it. This phenomenon is called retrieval practice and is supported by an extensive research literature mostly carried out in normal students. This paradigm begins to be used in cognitive remediation programs in patients suffering from memory difficulties. The objective of this study is to investigate whether retrieval practice is spared in patients with schizophrenia. If effective, this method could be used in cognitive remediation programs. Since episodic memory difficulties are supposed to be secondary to deficits in the initiation/elaboration of efficient encoding and retrieval strategies our hypothesis is that retrieval practice is spared in schizophrenia.

Confabulators consistently generate false memories without intention to deceive and with great feeling of rightness. However, there is currently no known effective treatment for them. In order to fill this gap, the aim of this trial was to design a neuropsychological treatment based on the current theoretical models and test it experimentally in two groups of confabulators: experimental vs. control. The treatment consisted of some brief material that patients had to learn and recall at both immediate and delayed moments. After both recollections, patients were given feedback about their performance (errors and correct responses). Pre-treatment and post-treatment baselines were administered. Confabulators in the control group performed the baselines without treatment, and were then offered the treatment after the second baseline.

The investigators plan to investigate the effect of enhancement on working memory (WM) in patients of chronic schizophrenia and determine the predictive factors of effective treatment.
