ADHD Treatment in a 60-Year-Old Female
Start with long-acting stimulant medication—specifically lisdexamfetamine (Vyvanse) or extended-release methylphenidate (Concerta)—as first-line pharmacotherapy, as these achieve 70-80% response rates in adults with ADHD and provide consistent all-day symptom control with once-daily dosing. 1
First-Line Pharmacological Approach
Stimulants remain the gold standard for adult ADHD treatment regardless of age, with the largest effect sizes (approximately 1.0) and most robust evidence from over 161 randomized controlled trials. 1
Preferred Stimulant Options:
Lisdexamfetamine (Vyvanse): Start at 10 mg once daily in the morning, titrate by 5 mg weekly up to 50 mg maximum, with once-daily dosing improving medication adherence and providing prodrug formulation that reduces abuse potential. 1
Extended-release methylphenidate (Concerta): Provides around-the-clock coverage with OROS delivery system resistant to tampering, demonstrating response rates of 78% versus 4% with placebo when dosed at approximately 1 mg/kg total daily dose. 1
Amphetamine-based stimulants are preferred for adults based on comparative efficacy studies, though individual response to methylphenidate versus amphetamine is idiosyncratic—approximately 40% respond to both, 40% respond to only one. 1
Critical Monitoring Parameters:
Baseline and regular cardiovascular monitoring is mandatory: check blood pressure and pulse at baseline, at each medication adjustment, and periodically during stable long-term treatment. 1
Screen for contraindications: uncontrolled hypertension, symptomatic cardiovascular disease, active substance abuse disorder, and personal/family history of bipolar disorder. 1, 2
Monitor for common adverse effects: appetite suppression, weight loss, sleep disturbances, and anxiety—though these are typically manageable with dose adjustment or timing modifications. 1
Second-Line Non-Stimulant Options
If stimulants are contraindicated, not tolerated, or inadequately effective after trials of both methylphenidate and amphetamine classes:
Atomoxetine:
Initiate at 40 mg daily, increase after minimum 3 days to target dose of 80 mg daily (can be given as single morning dose or divided doses), with maximum of 100 mg daily. 1, 2
Requires 6-12 weeks to achieve full therapeutic effect with median time to response of 3.7 weeks, and probability of improvement may continue increasing up to 52 weeks. 1
Effect size approximately 0.7 compared to stimulants' 1.0, making it less effective but suitable for patients with substance abuse history, severe anxiety, or cardiovascular concerns. 1, 3
FDA black box warning for suicidal ideation: close monitoring required, especially during first few months or at dose changes. 1
Alpha-2 Adrenergic Agonists:
Extended-release guanfacine (1-4 mg daily) or clonidine demonstrate effect sizes around 0.7 and can be used as monotherapy or adjunctive therapy with stimulants. 1
Particularly useful if comorbid sleep disturbances, anxiety, or tics are present, with administration in the evening generally preferable due to somnolence/fatigue as adverse effects. 1
Require 2-4 weeks for full effect and provide 24-hour coverage without stimulant-related cardiovascular concerns. 1
Treatment Algorithm for Inadequate Response:
If response to one stimulant class is inadequate, trial the other class before abandoning stimulants entirely. 1
Optimize dosing: Many patients require higher doses than initially prescribed—for amphetamine salts, adults often need 20-40 mg daily, with maximum doses reaching 40-50 mg. 1
Consider adding afternoon/evening dose if morning long-acting formulation wears off before end of day, as ADHD requires consistent symptom control throughout the day to prevent functional impairment. 1
If two stimulant trials fail, switch to atomoxetine and allow adequate time (6-12 weeks) for full therapeutic effect. 1
If atomoxetine insufficient, trial extended-release guanfacine or clonidine, allowing 2-4 weeks for treatment effects. 1
Adjunctive Non-Pharmacological Interventions:
Cognitive Behavioral Therapy (CBT) is the most extensively studied psychotherapy for adult ADHD, focusing on time management, organization, planning, and adaptive behavioral skills, with increased effectiveness when combined with medication. 1
Mindfulness-Based Interventions show increasing evidence for managing adult ADHD, helping most profoundly with inattention symptoms, emotion regulation, executive function, and quality of life. 1
Special Considerations for Older Adults:
Long-term methylphenidate treatment is appropriate for adults who continue to demonstrate functional impairment, with a 7-week randomized discontinuation study demonstrating that patients on methylphenidate for more than 2 years experienced significant symptom worsening when medication was stopped. 1
Do not discontinue effective ADHD treatment solely due to concerns about "taking medication forever", as untreated ADHD is associated with increased risk of accidents, substance abuse, criminality, and functional impairment. 1
Establish systematic monitoring schedule with periodic cardiovascular assessments during stable long-term treatment, and initiate or intensify antihypertensive therapy when needed. 1
Common Pitfalls to Avoid:
Do not assume the patient is "too old" for stimulants—age alone is not a contraindication, and stimulants remain first-line treatment with proper cardiovascular screening. 1, 4
Do not underdose stimulants—systematic titration to optimal effect is more important than strict mg/kg calculations, with 70% of patients responding optimally when proper titration protocols are followed. 1
Do not prescribe immediate-release formulations for "as-needed" use—ADHD requires consistent daily treatment, and long-acting formulations provide better adherence, more consistent symptom control, and lower diversion potential. 1
Do not assume bupropion or other antidepressants are equivalent to stimulants—these are explicitly second-line agents with smaller effect sizes and should only be considered after stimulant trials fail or are contraindicated. 1
