d i t o r i a lDear
Colleagues,Disorders
observed in the elderly have become a major focus of interest in clinical med-icine and research. The demographic
trends of the early 21st century, predicting a higher pro-portion of healthy retirees in the population, further
emphasize the importance of geriatricneurology
and psychiatry. A child born in the West in 1900 could expect to live 45
years, com-pared
with approximately 80 years for his counterpart born today. Although life
expectancyremains
shorter in developing countries, it has increased also linearly over the
last decades,following
a curve that parallels the changes observed in affluent countries.This issue was coordinated by Barry
Lebowitz, Director of the Adult and Geriatric Treat-ment and Preventive Interventions Research
Branch at the National Institute of MentalHealth
in Bethesda, Maryland. A review of the current state of research into
cognition andthe
aging brain is offered. A variety of topics are covered, such as models
of cognitive func-tion, the
impact of medications on cognition in the elderly, the treatment of cognitive
deficits,the
metabolic and neuroanatomic manifestations of aging, or the modifications
of neuroen-docrine
and sleep functions.Much
of the research discussed here is in a state of flux; new findings and hypotheses
arebeing presented
every day. A characteristic of geriatric psychiatry is the intricate mixture
ofsomatic and
mental factors. Similarly, treatment often relies on combined approaches, includ-ing pharmacological agents and behavioral
and psychotherapeutic techniques (eg, cognitivetherapy). We
hope that todays research and new pharmaceutical compounds will helpimprove the well-being of our patients
in a not too distant future.Yours
sincerely,Jean-Paul
