28. Neuropsychiatric and Cognitive Management

Neuropsychiatric symptoms are common in atypical parkinsonism (CBS/PSP) and significantly impact quality of life. This section covers pharmacological and non-pharmacological approaches to manage cognitive decline, mood disorders, psychosis, and behavioral symptoms.

28.1 Cognitive Enhancers

Cognitive impairment in CBS/PSP involves executive dysfunction, apraxia, and visuospatial deficits. Standard AD medications have limited but relevant utility.

28.1.1 Cholinesterase Inhibitors

Evidence Summary:

  • Donepezil showed modest cognitive benefits in PSP in a 24-week RCT1

  • Cholinesterase inhibitors may worsen parkinsonism in some patients — monitor closely

  • BuChE inhibition (rivastigmine) may be more relevant as BuChE activity increases with neurodegeneration

NET Assessment:

  • Consider donepezil 5-10mg daily if cognitive symptoms are prominent

  • Start low (5mg), titrate slowly

  • Monitor for GI side effects, bradycardia

28.1.2 Memantine

Evidence: A small crossover trial in PSP showed no cognitive benefit but some behavioral improvement2

NET Assessment: Low priority — limited efficacy; may try if cholinesterase inhibitor not effective

28.2 Mood Stabilizers and Antidepressants

Depression and anxiety are common in CBS/PSP and require careful management given medication interactions.

28.2.1 SSRIs

Important: SSRIs have minimal interaction with levodopa/rasagiline. Avoid MAOIs (phenelzine, tranylcypromine) due to serotonin syndrome risk with MAO-B inhibitors.

28.2.2 Other Antidepressants

NET Assessment: Sertraline or venlafaxine are first-line for depression. Avoid tricyclics (amitriptyline) due to anticholinergic effects and confusion risk.

28.2.3 Mood Stabilizers

Note: Lithium requires careful monitoring (thyroid, kidney). May have neuroprotective properties relevant to tauopathy.

28.3 Antipsychotics for PD/PSP/CBS

Psychosis (hallucinations, delusions) is challenging — standard antipsychotics worsen parkinsonism. The following are dopamine D2-preserving options.

28.3.1 Pimavanserin (Nuplazid)

Evidence: CLARITY trial showed significant reduction in psychosis without worsening motor symptoms3

Dosing: 34mg daily (start with 34mg, no titration needed)

NET Assessment: Strong recommendation — first-line for psychosis in PD/PD+ (may help CBS/PSP)

28.3.2 Quetiapine (Seroquel)

Dosing: 12.5-50mg nightly (start low, titrate as needed)

NET Assessment: Second-line if pimavanserin unavailable or ineffective

28.3.3 Clozapine (Clozaril)

Dosing: 6.25-50mg nightly (requires REMS program)

NET Assessment: Third-line — most effective but requires monitoring

28.3.4 What to AVOID

28.4 Sleep Medications

Sleep disturbances are common in CBS/PSP — RBD, insomnia, and fragmented sleep. Management requires careful medication selection.

28.4.1 Insomnia

28.4.2 REM Behavior Disorder (RBD)

RBD in CBS/PSP is typically treated with:

Important: Clonazepam (a benzodiazepine) should be used cautiously in elderly CBS/PSP patients due to fall risk and confusion. Melatonin is often preferred.

28.4.3 Excessive Daytime Sleepiness (EDS)

28.5 Anxiety Management

Anxiety in CBS/PSP may be secondary to neurodegeneration, medication effects, or reaction to diagnosis.

28.5.1 Non-Pharmacological

28.5.2 Pharmacological

NET Assessment: Prioritize non-pharmacological approaches. SSRIs for chronic anxiety.

28.6 Behavioral Interventions

Non-pharmacological approaches are critical for neuropsychiatric symptoms in CBS/PSP.

28.6.1 Cognitive Behavioral Therapy (CBT)

  • Effective for depression, anxiety, and adjustment disorder

  • Helps patient cope with diagnosis and functional decline

  • Available via telehealth

28.6.2 Occupational Therapy (OT)

  • Addresses functional independence

  • Environmental modifications

  • Fall prevention strategies

28.6.3 Speech Therapy

  • Address dysarthria, dysphagia

  • LSVT LOUD® for voice changes

28.6.4 Caregiver Support

Caring for someone with CBS or PSP presents unique challenges due to the progressive nature of these conditions, the cognitive and behavioral changes, and the complex care needs. Supporting caregivers is essential for maintaining quality of life for both patient and caregiver.

28.6.4.1 Caregiver Burnout

Caregiver burnout is a state of physical, emotional, and mental exhaustion that occurs when caregivers do not receive the help they need or try to do more than they are able.

Warning Signs:

  • Chronic fatigue, sleep disturbances

  • Irritability, anger, or resentment toward the patient

  • Neglecting own health and medical needs

  • Withdrawal from friends, family, and previously enjoyed activities

  • Feelings of hopelessness, depression, or anxiety

  • Increased use of alcohol or substances

Prevention Strategies:

  • Set realistic expectations about disease progression

  • Accept that you cannot provide all care alone

  • Maintain personal health routines (exercise, sleep, nutrition)

  • Stay connected with friends and support networks

  • Seek professional help when needed

28.6.4.2 Support Groups

28.6.4.3 Respite Care Options

Respite care provides temporary relief for caregivers, allowing them to take breaks while ensuring their loved one receives proper care.

Finding Respite Services:

Medicare/Medicaid:

  • Medicare may cover limited respite under certain conditions

  • Medicaid waiver programs often include respite benefits

  • Long-term care insurance may cover respite

28.6.4.4 Home Health Aides

  • Celebrate small victories and moments of connection

Practical Coping:

  • Use a caregiving notebook or app to track medications, appointments

  • Create a daily routine — structure provides predictability

  • Prepare simple meals in advance

  • Accept help when offered — make specific requests

  • Use adaptive equipment to make tasks easier

Building a Support System:

  • Identify family members who can help regularly

  • Create a care team (family, friends, professionals)

  • Connect with community resources (church, senior centers)

  • Maintain at least one friendship outside of caregiving

Self-Care Non-Negotiables:

  • Schedule regular exercise (even 10-minute walks help)

  • Prioritize sleep hygiene

  • Eat regular, nutritious meals

  • Keep up with own medical appointments

  • Take breaks every single day, even if brief

  5. Anxiety: CBT first-line; SSRIs for persistent symptoms

  6. Avoid: Haloperidol, risperidone, olanzapine — all worsen parkinsonism

36. Pain Management for CBS/PSP

Pain is a common and debilitating symptom in corticobasal syndrome (CBS) and progressive supranuclear palsy (PSP), affecting up to 70-80% of patients. It results from multiple mechanisms including musculoskeletal strain from rigidity and dystonia, radiculopathy from spinal degeneration, and central pain syndromes from thalamic or cortical involvement.

36.1 Types of Pain in CBS/PSP

36.2 Pharmacological Management

First-Line Agents

Second-Line Agents

Agents to Use with Caution

  • Clonazepam: May help RBD and myoclonus but causes sedation/falls in CBS/PSP

  • Baclofen: Muscle relaxant; may worsen weakness, cause sedation

  • TCAs (amitriptyline): Anticholinergic effects worsen confusion/cognitive issues

36.3 Non-Pharmacological Approaches

36.4 Pain Assessment Tools

36.5 Treatment Algorithm

Initial Assessment
       ↓
Mild (VAS 1-3): Acetaminophen + PT + Heat/Ice
       ↓
Moderate (VAS 4-6): Add gabapentin or duloxetine + non-pharmacological
       ↓
Severe (VAS 7-10): Consider tramadol/oxycodone + multidisciplinary approach
       ↓
Refractory: Referral to pain management specialist

36.6 Drug Interactions with Current Medications

36.7 Recommendations for This Patient

  1. Start with gabapentin 300mg daily, titrating to 300mg TID as tolerated

  2. Add duloxetine 30mg daily if depression co-occurs or gabapentin insufficient

  3. Avoid tramadol due to MAO-B interaction risk with rasagiline

37. Alternative and Complementary Therapies for CBS/PSP

Complementary and alternative medicine (CAM) approaches offer supportive benefits for patients with corticobasal syndrome (CBS) and progressive supranuclear palsy (PSP). While these therapies do not modify disease progression, they may improve quality of life, reduce symptom burden, and provide psychological benefits. This section reviews the evidence for various CAM modalities relevant to CBS/PSP.

37.1 Overview of CAM in Neurodegeneration

The use of complementary therapies among patients with movement disorders is common, with surveys indicating 40-60% of PD patients use some form of CAM4. In CBS/PSP, where conventional treatments offer limited symptomatic relief, patients often seek additional supportive options.

Potential Benefits:

  • Symptom palliation (pain, anxiety, sleep disturbance)

  • Enhanced wellbeing and quality of life

  • Reduced reliance on pharmacological interventions

  • Psychological support and coping strategies

Important Considerations:

  • CAM approaches should complement, not replace, evidence-based treatments

  • Some herbs/supplements may interact with prescribed medications

  • Quality and standardization of CAM products varies widely

  • Individual responses are highly variable

37.2 Acupuncture

Acupuncture, a key component of Traditional Chinese Medicine (TCM), involves stimulating specific points on the body to promote energy flow and restore balance. It has been studied extensively in Parkinson’s disease, with emerging evidence in CBS/PSP.

Evidence Summary

Key Trials:

  • A 2021 meta-analysis of 13 RCTs in PD (n=805) showed acupuncture significantly improved UPDRS Part III scores (MD = -4.42, 95% CI -6.18 to -2.66)5

  • A 2022 randomized sham-controlled trial (n=120) found real acupuncture superior for motor function and quality of life in PD6

  • No large-scale RCTs specifically in CBS/PSP, but mechanistic studies suggest benefit for rigidity and gait

Mechanism of Action

Acupuncture may exert effects through:

  • Modulation of dopaminergic activity in the basal ganglia

  • Reduction of neuroinflammation via cytokine regulation

  • Endorphin release and pain modulation

  • Autonomic nervous system regulation

Commonly Used Acupoints in Movement Disorders

Safety Considerations

  • Generally safe when performed by qualified practitioners

  • Avoid needling into areas of contusions, infection, or lymphedema

  • Caution with anticoagulation (risk of bruising)

  • Electroacupuncture contraindicated with pacemakers

  • Potential herb-drug interactions if using herbal preparations concurrently

Recommendations for This Patient

  1. Try acupuncture — reasonable option given moderate evidence in PD; likely similar benefit in CBS/PSP

  2. Frequency: 1-2 sessions per week for 8-12 weeks, then maintenance

  3. Select qualified practitioner: Look for licensed acupuncturist with experience in neurological conditions

  4. Coordinate with neurologist — inform treating physician

  5. Start with 2-3 points and titrate based on tolerance

30. Autonomic Dysfunction Management

Autonomic dysfunction is common in atypical parkinsonism (CBS/PSP) and significantly impacts quality of life. Management focuses on symptomatic relief while avoiding medications that may worsen other symptoms or interact with dopaminergic therapies.

30.1 Orthostatic Hypotension

Orthostatic hypotension (OH) is a drop in blood pressure upon standing (>20 mmHg systolic or >10 mmHg diastolic). It causes dizziness, falls, and presyncope.

Non-Pharmacological Management:

  • Increase fluid intake (2-3 L/day) and salt intake

  • Compression stockings (waist-high, 30-40 mmHg)

  • Head-of-bed elevation (30°) to reduce nocturnal diuresis

  • Slow, gradual position changes

  • Avoid large meals (postprandial hypotension)

  • Exercise in recumbent or seated position

Pharmacological Options:

Drug Interactions with Current Medications:

  • Levodopa: Can cause or worsen OH via peripheral vasodilation; timing separation helps

  • Rasagiline (MAO-B inhibitor): Risk of hypertensive crisis with sympathomimetics; avoid midodrine within 14 days of MAO-Bi or use cautiously

RECOMMENDATION for this patient:

  • Start with non-pharmacological measures (compression stockings, hydration)

  • If insufficient, consider fludrocortisone 0.1 mg/day with monitoring of BP supine/standing

  • Midodrine 5 mg PRN for breakthrough symptoms (avoid evening doses)

  • Monitor for worsening of supine hypertension

30.2 Constipation

Constipation affects up to 80% of PSP/CBS patients due to autonomic dysfunction and reduced mobility.

Management Approach:

Prokinetic Considerations:

  • Metoclopramide: Also used for levodopa-induced nausea; may worsen parkinsonism (central D2 blockade) — use with caution short-term only

  • Domperidone: Prokinetic without central effects; available in Canada/EU; not FDA-approved in US

  • Erythromycin: Macrolide antibiotic with motilin agonist activity; tolerance develops quickly

Drug Interactions:

  • Levodopa absorption may be reduced by delayed gastric emptying; consider taking levodopa 30-60 minutes before prokinetics

  • Fiber supplements may reduce absorption of levodopa; separate doses by 2 hours

RECOMMENDATION:

  • Start with polyethylene glycol 17 g daily + increased fiber/fluids

  • Add sennosides PRN if inadequate

  • Consider prucalopride 2 mg daily if refractory

  • Physical activity as tolerated

30.3 Urinary Dysfunction

Urinary symptoms in CBS/PSP include urgency, frequency, nocturia, and incomplete emptying.

Overactive Bladder (OAB) Management:

For Incomplete Emptying (Detrusor Underactivity):

  • Clean intermittent catheterization

  • α1-blockers (tamsulosin) — may worsen orthostatic hypotension

  • Cholinergic agonists (bethanechol) — limited efficacy

Drug Interactions:

  • Antimuscarinics may reduce levodopa absorption (gastric motility effects)

  • Trospium: reduced CNS side effects preferred in cognitively vulnerable patients

RECOMMENDATION:

  • Start with trospium 20 mg BID or solifenacin 5 mg daily (less cognitive impact)

  • If inadequate and cognitive status stable, consider antimuscarinic + behavioral therapy

  • Monitor for worsening constipation (antimuscarinics)

  • Urology referral if incomplete emptying suspected

30.4 Sexual Dysfunction

Sexual dysfunction is underreported but common. May include decreased libido, erectile dysfunction, or hypersexuality (usually medication-induced).

Erectile Dysfunction:

Drug Interactions:

  • PDE5 inhibitors: Contraindicated with nitrates; caution with α-blockers (additive hypotension)

  • Midodrine may improve erectile function (enhances perfusion)

RECOMMENDATION:

  • Screen for sexual dysfunction as part of autonomic review

  • Rule out medication-induced causes (dopamine agonists can cause hypersexuality)

  • If present, sildenafil 50 mg PRN with BP monitoring

30.5 Sweating Abnormalities

Excessive sweating (hyperhidrosis) or anhidrosis (absent sweating) both occur.

Hyperhidrosis Management:

  • Topical antiperspirants (aluminum chloride 10-20%)

  • Botulinum toxin injections (effective but costly)

  • Glycopyrrolate 1-2 mg TID (antimuscarinic)

  • Low-dose clonidine 0.1-0.3 mg TID (central sympatholytic)

Anhidrosis Management:

  • Heat avoidance; cooling strategies

  • Monitor for overheating

  • No specific pharmacological treatment

30.6 Autonomic Testing Recommendations

118. Patient-Reported Outcomes and Quality of Life Metrics for CBS/PSP

Patient-reported outcomes (PROs) are critical for capturing the subjective experience of patients with corticobasal syndrome (CBS) and progressive supranuclear palsy (PSP), complementing objective clinical measures. This section covers PRO instruments validated or under development for tauopathies, quality of life assessments, caregiver burden measures, and strategies for integrating patient preferences into treatment decisions for this CBS/PSP patient.

118.1 Overview of Patient-Reported Outcomes in Tauopathies

PROs provide direct measurements of patient health status that come directly from the patient without interpretation by clinicians or others. In CBS and PSP, PROs are particularly valuable because:

  1. Subjective symptom burden — Patients experience fatigue, pain, cognitive difficulties, and mood changes that may not be captured on standard scales

  2. Functional impact — Activities of daily living (ADLs), instrumental ADLs (IADLs), and quality of life are central to patient wellbeing

  3. Treatment response — Patient perception of benefit/side effects guides therapeutic decisions

  4. Progressive disease course — Longitudinal PRO collection tracks functional decline and intervention effects

118.2 PRO Instruments Validated for CBS/PSP

Movement Disorder-Specific Instruments:

CBS/PSP-Specific Instruments:

Generic PRO Instruments:

118.3 Quality of Life Assessment in CBS/PSP

Core Quality of Life Domains for This Patient:

Quality of Life Impact by Disease Stage:

118.4 Caregiver Burden and Family Impact

Caregiver Burden Assessment Tools:

Caregiver Burden in CBS/PSP:

CBS and PSP impose significant caregiver burden due to:

  • Progressive motor impairment requiring physical assistance

  • Cognitive dysfunction affecting communication and safety

  • Neuropsychiatric symptoms (apathy, irritability, disinhibition)

  • 24-hour supervision needs in advanced disease

  • Sleep disruption from patient sleep disorders

Caregiver Support Interventions:

118.5 Integration of Patient Preferences into Treatment Decisions

  1. Elicit patient values — Discuss what’s most important: independence, cognition, mobility, longevity

  2. Present options — Explain benefits/risks of each therapeutic approach

  3. Discuss trade-offs — Help patient understand realistic expectations

  4. Document preferences — Record in medical record for care team

  5. Reassess periodically — Preferences may change with disease progression

Treatment Decision Matrix for This Patient:

Advance Care Planning:

For this patient, advance care planning should address:

  1. Goals of care — Preferences regarding aggressive interventions, code status

  2. Decision-making capacity — Identify surrogate decision-maker now

  3. Legal documents — Healthcare proxy, living will, power of attorney

  4. Future care preferences — Feeding tube, ventilation, hospitalization

  5. Hospice eligibility — Discuss when to transition to comfort care

118.6 Longitudinal PRO Tracking Protocol

Recommended Assessment Schedule:

PRO Collection Methods:

  1. In-clinic — Paper or tablet administration during visits

  2. Remote — Online patient portal, smartphone apps

  3. Caregiver-assisted — For patients with motor/cognitive limitations

118.7 NET Assessment for Patient-Reported Outcomes

Clinical Readiness Assessment:

NET Score: 43/60 (71.7%)

Clinical Recommendations:
