The cessation of any psychoactive substance can produce withdrawal effects and therefore many of the episodes of ‘relapse’ recorded Since their introduction in the 1950s, antipsychotic in patients on placebo may simply have been the drugs have been the mainstay of treatment for people manifestation of these effects. This is especially likely diagnosed with psychosis and schizophrenia, rapidly since withdrawal effects of antipsychotics include replacing the sedatives and physical treatments, agitation and insomnia, which may be classified as such as insulin coma and electroconvulsive therapy, relapse when relapse is defined, as it often is, by that were previously used (Moncrieff 2008).

Long-term use is associated with disabling and life-threatening effects How drugs function such as tardive dyskinesia and metabolic syndrome. General assumptions about psychiatric drugs The drugs also increase the risk of premature death and how they act have obscured the nature more than twofold (Joukamaa 2006) and brain of antipsychotics. The orthodox view is that imaging studies suggest that they may reduce psychiatric drugs work by reversing or improving brain volume after only a few weeks of treatment an underlying neurochemical process that produces (Lieberman 2005).

However, the replication of this the intensity of psychotic symptoms by dampening trial in Sweden failed to achieve such high levels down all mental activity. Although it is clear that of avoidance of drug treatment, with only 19% of such a state may be helpful at times, it is also likely participants remaining drug-free (Cullberg 2002). to be unpleasant and disabling. In addition, viewing This may be because of decreased efforts to avoid psychiatric drugs as drugs (as extrinsic substances drug treatment and suggests a continuing need for that alter the way the body functions) highlights reinforcement of the rationale of the minimal-drug their capacity to produce adverse effects and changes approach. the way that we evaluate them.

However, there are many others who Other approaches may be able to endure and survive their psychosis Assessing Soteria without the use of these often unpleasant and potentially harmful drugs. The Soteria and It is therefore imperative that we devise alternative Scandinavian experiments suggest that psychosis strategies for helping people who suffer psychotic may be managed successfully using lesser quantities episodes. The article by Calton & Spandler (2009, of antipsychotic drugs than are currently used and this issue) is to be welcomed for focusing our avoiding them altogether in one-third or more of attention on studies of treatment approaches that patients. Further research is needed to confirm aim to minimise or avoid the use of antipsychotic their results. In particular, pragmatic studies in medication. The largest of these, the US Soteria real-life settings are needed to assess the feasibility Project, was well designed with random or alternating of minimal-medication approaches and help to allocation, but a limitation of the experiment was identify factors that might predict who is most likely that people who were judged to be unmanageable to benefit from avoiding antipsychotic medication. in a Soteria setting were excluded from allocation However, the onus should not be on minimal- and a number of other participants dropped out medication approaches to prove their success, but during the early stages of the experiment. The data on the standard drug-focused approach to prove its certainly suggest that the Soteria Project was at superiority and to demonstrate that this superiority least as good as treatment as usual in terms of adequately compensates for the recognised negative 2-year outcomes (Bola 2003). However, the claim effects of antipsychotic treatment. that residents of the Soteria communities had There is no reason why antipsychotics should superior outcomes is more difficult to evaluate, be used universally and many reasons why they since it is based on a complex statistical analysis should be avoided if possible. Projects that attempt involving numerous outcome measures, which to minimise the use of antipsychotics should be might have resulted in false-positive results. The supported because evidence suggests that use of most important finding is that a high proportion of these drugs is not always necessary and because, Soteria-treated participants in the US study avoided as Calton & Spandler highlight, many patients and the use of antipsychotic drugs altogether (32% of carers want this choice. the intention-to-treat sample).
