Cognitive Disorders Delirium Dementia Amnestic Disorders

Cognitive Disorders Group of conditions characterized by disruption of: Thinking Memory Processing Problem-solving Treatment requires compassion and understanding of clients and families Cognitive Disorders (DSM-IV-TR) Delirium Dementia Amnestic disorders

Is it Delirium or Dementia?   DEMENTIA Onset Rapid onset over short time (hours to days) Gradual deterioration of function (months to years) Clinical Manifestations Impaired (may fluctuate throughout the day) Memory Judgment Ability to focus Ability to calculate LOC Altered Restless / agitated Sundowning (confusion at night) Rapid personality change Some hallucinations /illusions Unstable vital signs (due to medical illness) Impaired (do not change throughout the day) Speech (aphasia) Ability to recognize familiar objects (agnosia) Executive functioning (managing daily tasks Movement (apraxia) LOC usually unchanged Sundowning Gradual personality changes Stable vital signs (unless another illness present) Cause Secondary to another medical condition Infection (older adults) Substance abuse Caused by chronic disease Alzheimer’s Chronic alcohol abuse May be caused by permanent head trauma Outcome Reversible ! (if prompt Dx and Tx) Irreversible and progressive

Stages of Alzheimer’s Disease Clinical Manifestations 1 No impairment Normal Functioning No memory problems No problems evident to provider 2 Mild cognitive decline May be normal age-related changes (early signs of Alzheimer’s) Forgetfulness (eyeglasses / wallet) No memory problems evident to provider / friends / co-workers 3 Mild cognitive deficits (memory/concentration) Measurable in clinical testing Mild deficits (losing /misplacing important objects Decreased ability to plan Decreased attention span Difficulty remembering words / names Difficulty in social or work situations 4 Moderate cognitive decline Clearly detected in clinical interview (mild / early stage Alzheimer’s) Personality changes (withdrawn / subdued) Obvious memory loss Limited knowledge/memory of recent occasions, events, personal history Difficulty with planning and organizing (bill paying / managing money) Difficulty with complex mental arithmetic 5 Moderately severe cognitive decline (moderate stage Alzheimer’s) Increasing cognitive deficits Unable to recall important details (address/phone number) Still able to remember information about self and family Disoriented to time and place 6 Severe cognitive decline (mid-stage Alzheimer’s) Worsening memory problems Loss of awareness of recent events and surroundings Can recall own name but not personal history Significant personality changes (delusions, hallucinations, compulsive behaviors) Wandering Requires assistance with ADLs Disrupted sleep/wake cycle Increased urinary and fecal incontinence Violent tendencies (potential danger to self and others) 7 Very severe cognitive decline (late-stage Alzheimer’s) Unable to respond to environment Unable to speak or control movement Unrecognizable speech Incontinence Requires assistance for eating / impaired swallowing Gradual loss of ability to move Stupor or coma Death (frequently related to choking or infection)

Amnestic Disorder May be secondary to substance abuse or other medical condition No personality change or impairment in abstract thinking Changes include: Decrease awareness of surroundings Inability to learn new information despite normal attention Inability to recall previously learned information Possible disorientation to time and place

Labs / Tests / Screening Tools Cognitive Disorders Labs and Diagnostic Tests Standardized Screening Tools See handouts! Chest / skull Xray EEG ECG Liver function studies Thyroid function studies Brain neuro-imaging (CT / PET scan) Urinalysis Serum electrolytes MMSE Mini-Mental State Exam FAST Functional Assessment Screening Tool Global Deterioration Scale Geriatric Depression Scale Short form Michigan Alcoholism Screening Test – geriatric version

Nursing Care & Communication Cognitive Disorders Self-Assessment Nursing interventions focused on protection from injury and promoting dignity and quality of life Room close to nurse’s station Low level visual and auditory stimuli Well-lit environment Room with windows Time orientation ID bracelet Restraints as last resort Medications PRN Agitation / anxiety Safe physical environment Memory aids Clocks/calendars/seasonal photos Eye glasses and hearing aids Consistent daily routine Consistent caregivers Adequate food and fluid intake Allow for pacing and safe wandering Cover/remove mirrors Decrease fear / agitation Calm and reassuring Don’t argue or question hallucinations / delusions Reinforce reality Orient to time/place/person Introduce self with each new contact Eye contact Short simple sentences Reminisce Short time frames for activities and instructions Limit numbers of choices (eating / dressing) Avoid abstract thinking situations Avoid confrontation Encourage family visitation

Medications Cognitive Disorders Common Meds (use with caution in patients with asthma/COPD – may cause bronchoconstriction) Aricept (donepezil) Exelon (rivastigmine) Razadyne (galantamine) Increase acetylcholine Improves ability to perform self-care Slows cognitive deterioration (mild to moderate dementia Side effects Nausea/diarrhea (about 10% of patients) Bradycardia Nursing interventions / client education Monitor GI side effects / fluid volume deficits Promote fluid intake Dosage may be titrated to reduce symptoms Monitor pulse (teach family if client at home) Clients should be screened for underlying heart disease Medication/Food Interactions NSAIDS (aspirin) May cause GI Bleeding Antihistamines/tricyclic antidepressants / antipsychotics Can reduce therapeutic effects of Aricept

Medication Nursing Considerations Cognitive Disorders Cholinesterase Inhibitors Start dosage low / gradually increase until side effects are no long tolerable med no longer beneficial Monitor for adverse side effects Reinforce patient and family teaching Taper med when discontinuing Prevents abrupt progression of symptoms Monitor ability to swallow tablets Meds are available in tables and oral solutions Aricept available in orally disintegrating tablet Administer with or without food Aricept has a long half-life (administered once daily at HS) Other cholinesterase inhibitors administered BID Namenda (memantine) Blocks calcium entry to nerve cells Slows down brain cell death Only med approved for moderate to severe stages of Alzheimer’s Can be used concurrently with cholinesterase inhibitor Administer with or without food Monitor for common side effects Dizziness Headache Confusion constipation

Alternative Therapies Alternative Therapies / After Discharge Care / Client Outcomes Cognitive Disorders After Discharge Care Educate family/caregivers Care methods Adapting home environment Ensure safe home environment Support caregivers Alternative Therapies Estrogen therapy (women) May prevent Alzheimer’s Not useful for decreasing effects of pre-existing dementia Ginkgo Biloba (herbal) Used by some to aid memory Potential interactions Bleeding (with antiplatelet meds) Risk for seizures (combined with anti-seizure medications (lowers seizure threshold) Client Outcomes Client will demonstrate improvement in cognition, memory, self care ability Client will remain free from injury

Quick Quiz! How does Exelon (rivastigmine) work? What are the benefits of the medication for the client?

Quick Quiz! A client who has moderately severe dementia is admitted to a long-term care facility. Which of the following findings should the nurse expect? _____ No change in LOC _____ Stable vital signs _____ Daily changes in behavior _____ Restlessness _____ Disorientation

Substance and Other Dependencies Substance Abuse Substance Dependence Non-Substance Dependency

Substance Abuse (Want It!) Repeated use of chemical substance Clinically significant impairment over 12 month period Includes at least one of the following Unable to perform normal home/school/work duties Taking part in hazardous situation/risky behaviors while impaired Driving Repeated problems caused by substance abuse Legal problems Losing job Missed time at work Continued use despite problems

Substance Dependence (Need It!) Repeated use of chemical substances Impairment over 12 month period Three or more of the following: Presence of tolerance Need for higher and higher dosages Withdrawal Stopping or reducing substance results in physical and psychological manifestations Tremors Headaches Substance taken in larger amounts or for longer time Continuing pain medication after pain ceased Persistent, but unsuccessful desire to control use Progressively more time spent using and recovering from use Reduction in social / occupational duties Continued use in the presence of related physical and psychological problems acknowledged by the client.

Non-Substance Related Dependency (Process Addictions) Dependence on a behavior Gambling Sexual behaviors Shopping / spending Internet use

Defense Mechanisms Substance and Other Dependencies Denial Most common “I can quit whenever I want!” “Smoking doesn’t really cause my problems!” Can prevent client from seeking help

Risk Factors Genetics Low self-esteem Predisposition Low self-esteem Low tolerance for pain/frustration Few life successes Risk-taking tendencies Sociocultural Theories Native Americans High alcohol abuse percentages Asian Groups Lower alcohol abuse percentages Older clients may have history of alcohol abuse or develop patterns of abuse later in life due to stressors Losing spouse Retirement Social isolation

Data Collection Nursing history should include the following: Type of substance or compulsive behavior Pattern and frequency of substance use Amount of substance used Age at substance abuse onset Changes in use patterns Periods of abstinence Previous withdrawal symptoms Date of last substance use / compulsive behavior Review of systems Black out or loss of consciousness Changes in bowel movements Weight loss / gain Stressful situations experienced Sleep problems Chronic pain Concern over substance abuse Cutting down on consumption behavior Older Adults Alcohol use leads to: Falls Injuries Memory loss Somatic reports (headaches) Sleep changes Dependence may include decreased ability for self care Urinary incontinence Signs of dementia May show clinical manifestations at lower dosages Exposure to multiple medications in addition to psychological changes (age-related) raises likelihood of adverse effects

CNS Depressants Can produce physiological and psychological dependence May have: (when taken concurrently) Cross tolerance (tolerant to the effects of a certain drug and develops a tolerance to another drug) Cross dependency ("addicted to everything”)  a person who is addicted to one drug (alcohol for example) can become addicted to any drug if they use it Addictive effect

Standardized Screening Tools Michigan Alcohol Screening Test (MAST) Addiction Severity Index Recovery Attitude and Treatment Evaluator Brief Drug Abuse Screen Test CAGE-AID Asks clients to determine how they perceive their current substance abuse See Handouts

Nursing Care (during treatment) Self-assessment (nurse) Feelings about abuses These can be transferred to the client Nonjudgmental approach by nurse is imperative Use open-ended questions (“When was your last drink?”) Focus on safety Safe environment Close observation Reorientation to time/place/person Adequate nutrition and fluid balance Low stimulation environment Administer withdrawal medications as prescribed Monitor for covert substance abuse during detox Provide emotional support (clients and families) Reinforce teaching about codependent behaviors Instruct clients and families Addiction Treatment goal of abstinence Remove meds in the home that are not being used No sharing of medications Begin developing motivation and commitment for abstinence and recovery Encourage self-responsibility Help clients develop an emergency plan (what to do and who to contact) Encourage attendance in self-help groups

Other Care and Treatment Dual diagnosis Both mental health and substance abuse problem Use team approach Individual psychotherapy Group therapy Family therapy Pharmacology Therapy Alcohol Withdrawal Valium, Ativan, Librium, Tegretol, Catapres Alcohol Abstinence Antabuse, ReVia, Campral Opioid Withdrawal Dolophine, Catapres, Subutex, Suboxone Nicotine Withdrawal Wellbutrin, nicotine replacement (Nicorette/Nicotrol) Nursing Considerations and Client Education: Monitor vital signs and neuro status Provide for client safety and implement seizure precautions Encourage adherence to treatment plan Advise clients taking Antabuse to avoid all alcohol Can lead to neuro and GI complications

Discharge Care and Client Outcomes Reinforce how to recognize S/S of relapse and factors that can contribute to relapse Reinforce cognitive-behavioral techniques to maintain sobriety and find pleasure in activities other than using substances Help client develop communication skills Encourage 12-step program The client will verbalize coping strategies to use in times of stress The client will remain substance free The client will remain free from injury The client will attend a 12-step program regularly

Eating Disorders Eating disorders recognized by DSM-IV-TR Anorexia Nervosa Bulimia Nervosa Mortality rate for eating disorders is high Suicide is a risk Treatment focuses on normalizing eating patterns and beginning to address issues raised by the illness Comorbidities include Major depressive disorder Dysthymia (50-75%) OCD Substance abuse Anxiety disorders

Anorexia Nervosa Preoccupation with food and eating rituals Voluntary refusal to eat Exhibit morbid fear of obesity Refusal to maintain minimally normal body weight (85% of expected normal weight for the individual) Body image disturbance Occurs most often in females Adolescence to young adulthood 5% to 10% of clients with anorexia are male Two types: Restricting type Drastic food restriction (no binging or purging) Binge-eating type Engages in binge eating or purging behaviors

Bulimia Nervosa Recurrent eating of large quantities of food over short period of time (bingeing) Followed by inappropriate compensatory behaviors to get rid of excess calories Self-induced vomiting (purging) Most clients maintain a normal or slightly higher weight Average age of onset in females = 15 to 18 years About 10% to 15% of clients are males Onset generally occurs between 18 – 26 years Binging with use of excessive exercise is most common Two types: Purging Type Self-induced vomiting, laxatives, diuretics and/or enemas Nonpurging Type: May compensate for binging through other means Excessive exercise Misuse of laxatives Diuretics Enemas

Risk Factors Female Male Family genetics Hypothalamic/neurotransmitter/hormonal/biochemical imbalance Disturbance in Serotonin Interpersonal relationships Psychological influences Rigidity/ritualism Separation/individualization conflics Feeling ineffective Helplessness Depression Distorted body image Environmental factors Pressure from society “the perfect body” History of being a “picky” eater during childhood Participation in athletics Elite level of competitition Male Participation in sport where lean body is prized or necessary Bicycling Wrestling History of obesity
