This book, which covers Visions and hallucinations, explains what causes them and summarises how many hallucinations have been caused by each event or activity. It also provides specific help with questions people have asked us, such as ‘Is my medication giving me hallucinations?’.

Even light exercise, such as the Chinese discipline of T'ai Chi, may have a beneficial effect on blood pressure in older adults, report a team from the Welch Center for Prevention, Epidemiology, and Clinical Research (Baltimore, MD, USA).

Tai Chi Exercise for Patients with Cardiovascular Conditions and Risk Factors: A Systematic Review
Gloria Y. Yeh, MD, MPH,1,3 Chenchen Wang, MD, MSc,2 Peter M. Wayne, PhD,1 and Russell Phillips, MD1,3

To conduct a systematic review of the literature evaluating tai chi exercise as an intervention for patients with cardiovascular disease (CVD) or with cardiovascular risk factors (CVRF).
We searched:

1) Medline, CAB Alt Health Watch, BIOSIS previews, Science Citation Index, EMBASE, and Social Science Citation Index from inception through October 2007;

2) Chinese Medical Database, China Hospital Knowledge, China National Knowledge Infrastructure, and China Traditional Chinese Medicine Database from inception through June 2005; and

3) performed hand searches at the medical libraries of Beijing and Nanjing Universities. Clinical studies published in English and Chinese including participants with established CVD or CVRF were included. Data were extracted in a standardized manner; 2 independent investigators assessed methodological quality, including the Jadad score for randomized controlled trials (RCT).
Twenty-nine studies met inclusion criteria: 9 RCT, 14 non-randomized studies (NRS), and 6 observational trials (OBS). Three studies examined subjects with coronary heart disease, 5 in heart failure, and 10 in heterogeneous populations that included those with CVD. Eleven studies examined subjects with CVRF (hypertension, dyslipidemia, impaired glucose metabolism). Study duration ranged from 8 weeks to 3 years. Most studies included <100 subjects (range 5–207). Six of nine RCTs were of adequate quality (Jadad ≥3). Most studies report improvements with tai chi, including blood pressure reductions and increases in exercise capacity. No adverse effects were reported.
Preliminary evidence suggests that tai chi exercise may be a beneficial adjunctive therapy for some patients with CVD and CVRF. Further research is needed.
