Trial summary

Memory is constituted by a set of mental abilities of information processing that will be available at a later time. Flawless performance depends on several brain systems and other cognitive domains. Normal aging is characterized by cognitive deficits that may worsen the production capacity and quality of life. Read more about this study

About this study

Official title: Effects of rTMS on the Cognition of Elderly With Cognitive Impairment no Dementia ( CIND )

Memory is constituted by a set of mental abilities of information processing that will be available at a later time. Flawless performance depends on several brain systems and other cognitive domains. Normal aging is characterized by cognitive deficits that may worsen the production capacity and quality of life. Such deficits represent variations of normal , and may stabilize,or even better progress. Include multiple cognitive domains, such as working and episodic memory, and attention. Despite the heterogeneity of the nature and severity of these deficits, common characteristics were observed in neuropsychological assessment of that population, for example, reduction in processing speed. There is an important gap in the therapeutic approach of these individuals.

Transcranial magnetic stimulation (TMS) is a noninvasive and promising intervention, with potential to improve memory and cognition activating networks that operate on memory or other networks that interfere with cognitive performance. The technique relies on generating a variable magnetic field originated from an alternating electric current applied to the human skull reaching focal cortical regions.

This study is a sham-controlled clinical trial, randomized, double-blind study. It will be evaluated the effects of repetitive transcranial magnetic stimulation (rTMS) on global cognition (memory, attention, language, executive functions, planning, logical reasoning, calculation and visual-spatial perception), especially memory, of elderly individuals with mild cognitive impairment, included in the domain of cognitive impairment no dementia (CIND).

III. Outcome measures:

Will be considered as an outcome measure a variation greater than or equal to 10% compared to baseline scores of neuropsychological tests, which will be applied on three occasions: immediately before (T0), after treatment (T2) and 4 weeks after the end of it (T3).

Questions about this trial

What is this clinical trial studying?

A study testing Repetitive transcranial magnetic stimulation in people with Mild Cognitive Impairment, run by University of Sao Paulo General Hospital at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 21 Apr 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Hellen Marra (55 11 3069-8159, hellen.marra@usp.br), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Repetitive transcranial magnetic stimulation improves memory in elderly with memory complaints (time frame: Neuropsychological tests: T1 - effects after rTMS, and T2: 4 weeks after rTMS). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
