Risk factors for subdural bleeding in elderly population

|April 7, 2015
Summary
Oral anticoagulant therapy is linked to a higher incidence of spontaneous subdural hematomas (SDH) in elderly patients. This retrospective study suggests a significant association, warranting further investigation into anticoagulant-related intracranial bleeds.
Area of Science:
- Neurosurgery
- Geriatrics
- Pharmacology
Background:
- Intracranial bleeds in the elderly often result from minor trauma or non-traumatic causes.
- Clinical observation suggests a link between anticoagulant therapy and subdural hematomas (SDH), particularly chronic or sub-chronic types.
Purpose of the Study:
- To investigate the association between oral anticoagulant therapy and the occurrence of spontaneous subdural hematomas in elderly patients.
Main Methods:
- A retrospective survey of medical documentation was conducted.
- Data from patients treated at the Neurosurgery Clinic of KBC Rijeka between 2011 and 2012 were analyzed.
- Statistical analysis, including the Fisher exact test, was employed.
Main Results:
- A significantly higher incidence of spontaneous subdural hematomas (SDH) was observed in patients using oral anticoagulation therapy (p < 0.01).
- The study confirmed a relationship between oral anticoagulant therapy and SDH, especially the spontaneous subgroup.
Conclusions:
- The findings support an association between oral anticoagulant therapy and spontaneous subdural hematomas in the elderly.
- Further, larger-scale studies are recommended to elucidate this relationship.

01:15Drug Dosing: Geriatric Patients
368
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...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
340
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...

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
817
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...

353
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
330
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...

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
