NCT00878735

Brief Summary

The purpose of this study is to evaluate the effects of a Zen meditation retreat (Sesshin) on psychophysiological parameters in healthy volunteers (regular meditators and non-meditators) and in cancer patients and to observe possible changes in the attentional circuitry (through functional Magnetic Resonance Imaging- fMRI) and in psychological tests (Beck Anxiety and Depression Inventories, Self-Compassion Scale, Mindfulness Attention Awareness Scale, Lipp Stress Scale for Adults).

Outcome Measures

Primary Outcomes (1)

  • To evaluate the neural correlates of performance modulation on an attention paradigm (the Stroop word-color task; SWCT) and on an emotional paradigm (the frustration paradigm) before and after a Zen meditation retreat.

    2 years

Secondary Outcomes (1)

  • Anxiety, stress and depression symptoms, self-compassion feelings and mindfulness state will also be evaluated in healthy volunteers and cancer patients.

Behavioral: Zen meditation

NO INTERVENTION

No meditation (no intervention; keep regular activities) or a resting group (this group stays at the same place of the retreat group, but only to rest)

Interventions

Zen meditationBEHAVIORAL

Zen meditation retreat (7 days: 5 days from 5:30 to 9:30 plus one day for adaptation and the departure day). The program starts everyday at 5:30 and finish at 9:30. In silence, the volunteers perform seating and walking meditation, stretching exercises, eating and all tasks in mindfulness.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Healthy volunteers:
  • Men or women
  • Left-handed or right-handed, as long as there are left-handed individuals in both groups for comparison
  • Ages between 18 and 65
  • No history of neurological or psychiatric problems, or use of controlled medication that might interfere with attention
  • No symptoms of claustrophobia
  • Written informed consent form to participate in the study
  • Cancer patients:
  • The same criteria that apply to healthy volunteers in addition to a diagnosis of neoplasia confirmed by biopsy
  • Volunteers should be undergoing post-therapeutical control, have no cure criteria yet, and not have been submitted to radio- or chemotherapy in the last three months

You may not qualify if:

  • Healthy Volunteers:
  • Chemical dependence, including nicotine and alcohol
  • Dementia or psychotic condition (established by a questionnaire)
  • Depression or use of antidepressants
  • Non-controlled severe organic disease that might interfere with the performance of the study, such as neoplasias, cardiopathies, digestive pathologies, diabetes mellitus type I or type II
  • Neoplasias in the central nervous system
  • Tremor or dystonia in cephalic segment that hinders the performance of the RMf study (tremor equal to or higher than 3 in each corporal segment, according to the UPDRS scale)
  • Fulfillment of any criterion of contraindication for the MR exam (for instance, use of pacemaker; intracranial aneurism clip; cochlear implants)
  • Presence of odontological devices that might disturb the magnetic field or any sources of variation of the magnetic susceptibility
  • Presence of lesion in the encephalic parenchyma in the structural images. Exception is made to discreet punctiform areas in the white matter or a discreet reduction in the encephalic volume.
  • Cancer patients:
  • All the healthy volunteers, except for those that fit in the item: "non-controlled severe organic disease that might interfere in the performance of the study, such"
  • The use of medication that acts on the central nervous system
