Objectives: To assess olfactory functions (threshold, identification, and hedonic valence) of depressed subjects before and after an 8-week trial of escitalopram and compare the results of responders and nonresponders. Methods: Fifty-two depressed subjects were recruited. Participants received escitalopram and were evaluated at two visits: baseline (V0) and week 8 (V8). They were categorized as responders (Montgomery-Åsberg Depression Rating Scale [MADRS] score reduction of > 50%) or nonresponders to treatment. Participants were evaluated with the Mini International Neuropsychiatric Interview (MINI) at V0 and, at V0 and V8, completed psychometric and olfactory assessments, including MADRS and the State-Trait Anxiety Inventory (STAI), as well as the Sniffin’ Sticks® test (threshold and identification tasks). The hedonic valence of smell was assessed on a 10-cm linear scale after presenting two pleasant and two unpleasant odors. Forty-three participants completed the study (24 responders and 19 nonresponders). The Mann-Whitney, chi-square, and Fisher’s exact tests were used to compare olfactory, clinical, and demographic variables between groups and within the same group at V0 and V8. The Spearman coefficient was used to calculate the correlation between clinical characteristics and olfactory variables. Results: The hedonic score of pleasant odors increased significantly between V0 and V8 only for responders (V = 61.5, p = 0.018), with no significant change in nonresponders (V = 90.5, p = 0.879). Comparison of olfactory performances between groups at V0 and V8 separately did not show a significant difference between responders and nonresponders to escitalopram. Olfactory threshold and identification scores were not different between V0 and V8 for responders or nonresponders. Conclusion: Depressed subjects have olfactory anhedonia, which appears to regress following a positive antidepressant response. Hedonic valence may be an indicator of cognitive changes associated with depression; improvement of this valence may indicate a clinical response to antidepressants.

CONTEXTO: A Seção de Psiquiatria Geriátrica da Associação Mundial de Psiquiatria (AMP), desde 1997, vem desenvolvendo Declarações de Consenso relevantespara a prática da Psiquiatria Geriátrica. Desde 2006, a Seção vem trabalhando para desenvolver uma Declaração de Consenso sobre Ética e Capacidade em pessoas idosas com transtornos mentais. MÉTODO: Uma Conferência de Consenso foi realizada em Praga em setembro de 2008. Organizada pela Seção de Psiquiatria da Pessoa Idosa da AMP, ela contou com a participação do International Council of Nurses, Alzheimer Europe e Alzheimer Disease International. Os participantes foram reconhecidos pela sua perícia nesse domínio e vieram de 11 países. Incluíam psiquiatras, uma neurologista, um enfermeiro e representantes de cuidadores familiares. RESULTADOS: Após dois dias de reuniões e debate, redigiu-se um rascunho da declaração que foi submetida para análise nas diversas organizações/associações que participaram da reunião. Após as sugestões finais recolhidas, um texto definitivo foi preparado em inglês e publicado. A presente versão em português é da responsabilidade de dois participantes lusófonos da reunião, que são também coautores da declaração de consenso final. CONCLUSÕES: Essa Declaração de Consenso oferece aos clínicos em saúde mental que cuidam de pessoas idosas com transtornos mentais, cuidadores, outros profissionais da saúde e o público em geral as definições e o debate sobre os princípios éticos que podem frequentemente ser complexos e desafiadores, apoiados em orientações práticas para satisfazer tais necessidades e padrões éticos e encorajar a boa prática clínica.

BACKGROUND: The World Psychiatric Association (WPA) Section of Old Age Psychiatry, since 1997, has developed Consensus Statements relevant to the practice of Old Age Psychiatry. Since 2006 the Section has worked to develop a Consensus Statement on Ethics and Capacity in older people with mental disorders. METHOD: A Consensus Conference was realized in Prague, September 2008. The meeting was organized by the WPA Section of Old Age Psychiatry, with the participation of International Council of Nurses, Alzheimer Europe and Alzheimer Disease International. Participants who are recognised for their expertise in this area came from 11 countries and include psychiatrists, a neurologist, a nurse and family caregiving representatives. RESULTS: After two days of debate a draft was prepared and submitted to the organizations/associations represented at the meeting. When their respective comments were collected, a final text was prepared and published originally in English. This Portuguese version was prepared by two members of the meeting who came from Portuguese spoken countries. DISCUSSION: This Consensus Statement offers to mental health clinicians caring for older people with mental disorders, caregivers, other health professionals and the general public the setting out of and discourse in ethical principles which can often be complex and challenging, supported by practical guidance in meeting such ethical needs and standards, and to encouraged good clinical practice.

A Organização Mundial da Saúde (OMS) e a Seção de Psiquiatria da Pessoa Idosa da Associação Mundial de Psiquiatria (AMP), em colaboração com um grupo interdisciplinar de representantes das principais associações internacionais e organizações não-governamentais implicadas na saúde mental das pessoas idosas, publicaram três declarações técnicas de consenso sobre a psiquiatria da pessoa idosa (1), a organização dos cuidados em psiquiatria da pessoa idosa (2) e o ensino da psiquiatria da pessoa idosa (3). O Dia Mundial da Saúde 2001, cujo tema foi "Não à exclusão, sim aos cuidados", deu origem a uma nova reunião de consenso sobre o tema da estigmatização e discriminação das pessoas idosas com transtornos mentais. Essa nova reunião foi realizada em Lausanne nos dias 8 e 9 de outubro de 2001 e produziu uma declaração técnica de consenso. O texto inicial foi publicado pela OMS e AMP em inglês. Este artigo apresenta a versão em português desse documento.

This technical consensus statement is jointly produced by the Old Age Psychiatry section of the World Psychiatric Association and the World Health Organization, with the collaboration of several NGOs and the participation of experts from different regions. It is intended to be a tool for (i) promoting debate at all levels on the stigmatization of older people with mental disorders; (ii) outlining the nature, causes and consequences of this stigmatization; and (iii) promoting and suggesting policies, programs and actions to combat this stigmatization.
