Steroid Use in Patients with Dementia
Steroids are not recommended for the treatment of dementia as they provide no cognitive benefit and may potentially worsen cognitive function in patients with dementia. 1
Evidence Against Steroid Use in Dementia
- Systematic reviews have found no significant improvement in cognitive decline with steroid treatment for Alzheimer's disease 1
- Patients receiving steroids experienced more adverse effects including hyperglycemia, abnormal lab results, and facial edema compared to controls 1
- The 2014 U.S. Preventive Services Task Force review evaluated 26 studies on various medications including gonadal steroids and found no evidence that they provided any benefit in global cognitive or physical function in persons with mild to moderate dementia or MCI 2
Potential Risks of Steroid Use in Dementia Patients
- Research has identified a "steroid dementia syndrome" where certain individuals may develop cognitive impairment after glucocorticoid treatment 3
- Elderly women taking inhaled corticosteroids showed increased risk for cognitive decline over 7 years in executive functioning (odds ratio, 1.76; 95% confidence interval, 1.14-2.71) 4
- This risk increased with continuous use (odds ratio, 3.15; 95% confidence interval, 1.29-7.68) but was not found after discontinuation of treatment 4
- Case reports document patients developing dementia-like cognitive changes that appeared to result from steroid medications, with symptoms including deficits in memory retention, attention, concentration, mental speed and efficiency 5
Recommended Approaches for Dementia Management
Pharmacological Options
- Cholinesterase inhibitors (donepezil, galantamine, rivastigmine) should be considered in patients with mild to moderate Alzheimer's disease 2
- Vitamin E (1,000 IU orally twice daily) should be considered to slow progression of Alzheimer's disease 2
- Memantine may be considered for moderate dementia 2
- For neuropsychiatric symptoms, antipsychotics should be used to treat agitation or psychosis in patients with dementia when environmental manipulation fails 2
- Atypical agents (risperidone, olanzapine, quetiapine) may be better tolerated than traditional agents like haloperidol 2
- Selected antidepressants should be considered for treating depression in individuals with dementia 2
Non-Pharmacological Approaches
- Exercise (group or individual physical exercise) is recommended for people living with dementia 2
- Group cognitive stimulation therapy should be considered for people with mild to moderate dementia 2
- Psychosocial and psychoeducational interventions for caregivers of people living with dementia are recommended 2
- Behavior modification, scheduled toileting, and prompted voiding should be used to reduce urinary incontinence 2
- Graded assistance, practice, and positive reinforcement should be used to increase functional independence 2
Special Considerations for Steroid Use When Medically Necessary
If steroids must be used for other medical conditions in patients with dementia:
- Use the lowest possible dose for the shortest duration 2
- Monitor closely for worsening cognitive function 4
- Consider gradual tapering when discontinuing steroids 2
- Be aware that cognitive effects may be reversible after discontinuation or reduction of steroid medications 5
- Patients with pre-existing conditions like diabetes mellitus or immunocompromised status and the elderly will need special attention when steroids are necessary 2
Conclusion for Clinical Practice
When managing patients with dementia, clinicians should avoid prescribing steroids whenever possible due to lack of benefit and potential harm to cognitive function. For conditions requiring steroid treatment in dementia patients, careful monitoring of cognitive status is essential, with consideration of alternative treatments when available.
