NCT01207219

Brief Summary

The current study aims to evaluate the impacts of yoga and aerobic exercise on neuro-cognitive function, symptoms and brain changes in early psychosis. A total of 120 female subjects who aging from 18-55 years old, and diagnosed with psychotic disorders within the past 5 years, will be randomized into 3 groups: 1) yoga therapy, 2) aerobic exercise, and 3) waitlist group as the control. All groups will try to be kept consistent with their medication with no more than 25% change in their entry level dosage for at least six weeks. The primary outcomes of the present study will be neuro-cognitive changes; the secondary outcomes will be changes of brain structure and function.

Outcome Measures

Primary Outcomes (4)

  • Verbal Acquisition

    Total number of corrected encoded words in the first three trials in the random condition of Hong Kong List Learning test.

    baseline and 12 weeks

  • Verbal Retention

    The total number of correctly recalled words after short-term (10 minutes) and long-term (30 minutes) delay in the random condition of Hong Kong List Learning test.

    baseline and 12 weeks

  • Working Memory

    measured by Digit Span backwards test. In this test, the subject was asked to recall a series of numbers in reverse order. The correctly recalled series were scored as 1, and the test contains 14 sequences of numbers. The range of working memory score is from 0 to 14, with higher values representing better outcome.

    baseline and 12 weeks

  • Attention and Concentration

    measured by Letter Cancellation test Q score. The basic version of the task consists of six 52-character rows in which the target character is randomly interspersed approximately 18 times in each row. Subjects were asked to cancel the letter "C" and "E" as quickly as possible. The time to completion, number of error and omission items were recorded. A "quality of search" index (Q), developed by Geldmacher et al., was applied for the analysis. Q is the ratio of correct number to total number of targets multiplied by the ratio of correct number per second. Higher Q scores represent more efficient performance and better attention and concentration. Q scores could range from 0 (worst possible outcome) to 1 (best possible outcome).

    baseline and 12 weeks

Secondary Outcomes (1)

  • Severity of Symptoms

    Baseline and 12 weeks

Study Arms (3)

Yoga therapy

EXPERIMENTAL

Hatha yoga including breathing control (10 minutes), body posture(40-45minutes), and relaxation (5 minutes).

Aerobic exercise

EXPERIMENTAL

Aerobic exercise includes walking on the treadmill for 15-20 minutes and stationary cycling for 25-30 minutes.

Behavioral: Aerobic exercise

Waitlist group

NO INTERVENTION

Patients in waiting list will be treated as usual and acted as control group.

Interventions

Yoga therapyBEHAVIORAL

3 sessions per week for 12 weeks, total 36 sessions. Each session lasts around one hour.

Eligibility Criteria

Age18 Years - 55 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Females aged from 18 to 55.
  • Based on the Diagnostic and Statistical Manual (DSM-IV) diagnosed to have schizophrenia, schizoaffective disorder, schizophreniform Psychosis, brief psychotic disorders, psychosis not otherwise specified and delusional disorder. Duration of illness is less than 5 years (including 5 years).
  • Cantonese-speaking Chinese.
  • Ability to understand the nature of the study and to give an informed consent.
  • Fewer than 10 hours of yoga and vigorous aerobic exercise (equivalent to jogging at 10 km/hr) in the previous 3 months.

You may not qualify if:

  • Severe physical illness (myocardial infarction, hypertension, fracture, spinal problem), seizure disorders, mental retardation or comorbid substance dependence. Heart rate and blood pressure will be measured at the baseline to exclude the patients with abnormal cardiovascular activities.
  • Unstable psychotic symptoms.
  • Known pregnancy, or other contraindication to MRI.
  • A history of brain trauma or organic brain disease.
  • Known history of intellectual disability or special school attendance.
