Suicide & Life-Threatening Behavior
|January 1, 1992
Summary
Late-life suicide is understudied, yet involves serotonin system changes and impulsive violence. Further research into geriatric suicide biology, including degenerative diseases
Area of Science:
- Neuroscience
- Gerontology
- Psychiatry
Background:
- Suicide is a significant concern in all age groups, with a high percentage of completed suicides occurring in late-life.
- Existing biological research on suicide predominantly focuses on younger populations, neglecting the elderly.
- Serotonin system alterations are implicated in suicidal behavior across age groups.
Purpose of the Study:
- To review age-related changes in the central nervous system relevant to suicide biology.
- To examine post-mortem biological studies of suicide and suicide attempts in the elderly.
- To discuss the link between impulsive violence, degenerative diseases, and suicidal behavior in geriatric populations.
Main Methods:
- Review of existing literature on age-related central nervous system changes.
- Analysis of post-mortem brain studies of suicide victims and attempters.
- Discussion of biological studies on impulsive violence and the serotonin system in the context of aging and disease.
Main Results:
- Elderly suicide attempters often employ violent methods, suggesting a link to impulsive violence.
- Degenerative diseases may impact the serotonin system, potentially increasing suicidal behavior risk in older adults.
- There is a notable lack of biological research on suicide specifically within the geriatric population.
Conclusions:
- The biology of suicide in the elderly remains under-explored.
- Further investigation into the geriatric serotonin system and its relation to suicide is crucial.
- Understanding the impact of degenerative diseases on suicidal behavior in older adults is a key research priority.

01:15Drug Dosing: Geriatric Patients
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...
01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
