2 Objectives Briefly review issues related to sexuality in people with cognitive impairment Discuss the challenges in recognizing when sexual behavior is inappropriate Review current evidence for the management of inappropriate sexual behavior

3 Sexuality and Sexual Expression The basic need to belong, to be desired, to share oneself with another does not end with dementia. Sexuality is not what we do, but who we are.

4 Sexuality/Sexual Behavior Sexuality is a fundamental part of human existence. How we show closeness/express love.

5 Sexual Expression Sexually oriented expression: Words, gestures, or movements (including reaching, pursuing or touching) which appear to be motivated by the desire for sexual gratification) Holmes, D., Reingold, J., & Teresi, J. (1997)

6 Sexuality in Cognitive Impairment The need for close human contact does not decline with age or dementia Those with dementia communicate with behavior rather than speech Impact is often decreased sex drive Dementia deprives individuals of cultural norms

7 Myths 3 myths Older adults are not sexually desirable Older adults are not sexually desirous Older adults are not sexually capable

8

9 Normal Sexuality 60% of normal older persons have active interest in sexual activity. Stats from the NOCA 1998 survey report that 48% of men and women over 60 are sexually active.

10 Dispelling the Myths Men over age 60: 61% are sexually active 61% say sex is better or at least as satisfying as it was at % say sex is equally as emotionally satisfying as it was at 40 72% say sex is an important part of a relationship

11 Dispelling the Myths Women over 60 37% are sexually active 62% say sex is better or at least equally as physically satisfying as it was at % say sex is equally as emotionally satisfying as it was at % say sex is important in a relationship.

13 Inappropriate Sexual Behavior Focus on behaviors that are To unwanted inappropriate challenging Family Other residents Clinical staff / administrators Range of normal gets defined by the culture of the environment

14 Inappropriate Sexual Behavior Ozkan et al (2008) ISB grouped into 3 common types: Sex talk Most common Sexual acts Implied sexual acts pornography

15 Inappropriate Sexual Behavior Definition: No one recognized definition Encompasses range of behaviors such as: Verbal requests for sex Unwanted touching Masturbation Ambiguous behaviors (appearing naked or incompletely dressed) sexual disinhibition

16 Neurobiology Frontal system: disinhibition Normal etiquette may be forgotten Temporolimbic: hypersexual behavior Striatum: obsessive-compulsive sexual behavior Hypothalamus: increased sex drive Multiple neurotransmitter and hormonal systems

17 Scope of the Problem Not common (2.6-15%) Greater # in nursing homes Comprise an important component of BPSD defined as behaviors that are unsafe, disruptive and interfere with care (Ozkan et al 2008) Sex ratio unclear No differences based on type of dementia Low frequency but highly emotionally laden

18 Case of Mr. I.M. Proper 80 year old divorced man living in Level I care for several years. Progressive aphasia Very private person Referral At mealtime exposes himself to his female table partner

19 Is This Inappropriate Sexual Behavior?

20 Assessment of ISB Comprehensive exam including thorough sex history. Is this a new behavior?? Related to underlying cognitive changes or exacerbation of life-long characteristics? Related to underlying psychiatric disorder or use of dopamine agents?uti

21 Assessment of ISB Potential underlying causes: Unmet needs (toileting, UTI) Uncomfortable clothing (too tight, restrictive..) Misinterpretation (organic brain changes lead to misinterpretation of cues) Consider context: What is appropriate with one s partner (or willing other) is not appropriate with someone else

22 Assessment of ISB What is the target symptom? Specifically identify what the symptom and treatment goals are Who, what, when? Does behavior occur with all staff? One staff? Only men/women? During a particular activity, ie bathing?

23 Assessment of ISB Assessment (Litchenburg 1997, Litchenburg & Strzepek 1990) What form does behavior take? In what context? How frequently? What are contributing factors? Is there a problem? Whose problem is it? What are the risks involved? To whom? Are the participants competent?

24 Competency? No issue regarding consensual relationships between competent adults Setting dependent? Informed consent vs tacit consent? Specific competency Institutional policy Challenges?

25 Case of Mrs. Lonely 84 year old widow with 3 grown children who live out of the province. Always very proper. Moderately severesevere mixed dementia with persistent and rapid decline. Moved from assisted living to LTC, dementia care.

26 Case of Mr. Heart 80+ year old married man with 2 children living locally. Moderately severesevere AD

27 Case of Mr. & Mrs. Lonely- Heart Seen holding hands, sitting together, seeking each other out. Found lying on his bed together in an embrace, fully clothed.

28 Is This Inappropriate Sexual Behavior?

29 Ethics of ISB Guidelines for assessing appropriateness of relationship: awareness of relationship who is initiating relationship do they think this person is their spouse can they state what level of relationship they are comfortable with ability to avoid exploitation is this behavior consistent with formerly held values/beliefs can they say no Awareness of potential risks

30 Ethics of ISB Not overly realistic regarding relationships in advanced cognitive impairment.

31 Case of Mr. I.S. Bea 70 year never married man-was the favorite uncle of his nephews. Various careers which all involved public service. Moderate dementia, vascular with prominent disinhibition.

32 Case of Mr. I.S. Bea Frequent requests for sexual interaction with staff, verbally graphic, grabbing at breasts and crotch of female staff. Noted to be touching a co resident who was felt to be vulnerable due to cognitive and physical impairment. 1:1 caregiver for safety of co residents.

33 Is This Inappropriate Sexual Behavior?

34 Management of ISB Approach Define target behaviors Rule out delirium Review cognitive and sensory factors Review environmental factors Educate and support caregivers If fails Consider nonpharamacological approaches Consider drug therapy

35 Non Pharmacological Strategies Comprehensive review of Psychological approaches to the management of Neuropsychiatric symptoms of dementia (Livingston et al 2005): No one strategy was proven effective for any one type of behavior. Only behavior management therapies, specific types of caregiver/residential care staff education (and possibly cognitive stimulation) have any lasting effectiveness. Lack of evidence should not be interpreted as lack of efficacy.

36 Non Pharmacological Strategies Modification of social cues Environmental manipulation (ie rear closing clothing, objects to handle) Supportive psychotherapy (aimed at caregivers) Behavior Modification Change attitudes of staff/family

37 Non Pharmacological Strategies Avoid becoming angry or embarrassing the individual Seek a reason or explanation for behavior Gently, but firmly remind individual that behavior is inappropriate or unwanted

38 Non Pharmacological Strategies Try to increase level of appropriate affection hugging, hand holding, dancing Try distraction Remove to a private place Consider practical solutions rear access clothing Pink Panther tactile objects

39 Pharmacotherapy of ISB No one medication or class of medication has been proven effective for treatment of ISB No current medication has approval for use in these problems (off label use) No randomized, double blind, placebo controlled studies

40 What do you do?

41 Pharmacotherapy of ISB Goal is to suppress sexual fantasies, sexual urges and behaviors Case report / series evidence for Antidepressants Anticonvulsants Antipsychotics Anti-Dementia drugs Hormonal agents other

42 Antidepressants for ISB Generally used as first line agents but case report evidence only citalopram paroxetine sertraline clomipramine Case series for trazodone (Simpson et al, 1986) Antiobsessional and antilibidinal effects

43 Pharmacotherapy of ISB When 1 st line agents don t work? Debate in the literature Consider Antipsychotics Antiepileptics Antidementia drugs Hormone treatment

44 Antipsychotics for ISB No known clinical trials Case report evidence quetiapine haloperidol Thought to decrease ISB by their dopamine blocking effects and elevation of prolactin. Balance risk/benefit re:side effects

45 Mood Stabilizers for ISB Case reports for: gabapentin carbamazepine Mixed evidence for BPSD, no studies for ISB valproate lamotigine May be helpful because of mood stabilizing effect, antiandrogenic and antiprogestin effects.

46 Antidementia Drugs for ISB cholinesterase inhibitors rivastigmine case report donepezil case report - increased libido in 2 patients memantine: no current literature for ISB

47 Hormonal Agents for ISB Antiandrogens Medroxyprogesterone 3 small case series Cyproterone 2 case reports (female) decrease testosterone by inhibiting LH / FSH Estrogens DES or conjugated estrogen case report / series (38/39 pts) GnRH analogues leuprolide 2 case reports

48 Hormonal Agents for ISB Fully informed consent by legally authorized caregiver Ethical considerations US state regulators concerns re: chemical restraint Anderson Light & Holroyd (2006) 5 treatment refractory pts with ISB All improved with MPA 2 had med d/c because of state regulators-lost placements due to behavior.

49 Other drugs for ISB Cimetidine Retrospective chart review H2 receptor antagonist with antiandrogen effects Longterm use at high doses decreases testosterone binding to androgen receptor and inhibits the hydroxylation of estradiol Pindolol: Thought to work by decreasing adrenergic drive which decreases agitation, aggression and inappropriate behavior Case report

50 Choosing an agent Consider Target symptoms Urgency Goal of treatment Risk / benefit Informed consent Risk of not using any medications

51 History (Sexual, Medical, Psychiatric, Medications, Pre-morbid personality, Cognition, Functions) (Neurological disorders: Parkinson s, Multiple sclerosis, Huntington s, Stroke) Investigations (Blood tests, Urine examination, Vit B12 & folate levels, VDRL, and Neuroimaging) Treat disorder (Primary neuropsychiatric disorder, Delirium, Drug effect) Remove offending drugs Type of behaviors Inappropriate expression of normal sexual drive Inappropriate sexual behaviors Support expression of normal sexual drive Non-pharmacological management (Redirection, Privacy, Attire) Inadequate response Pharmacotherapy No confusion Confusion Cholinesterase inhibitors +/- Memantine Antipsychotics Psychotic Hypersexual Manic Anticonvulsant mood stabilizers /Impulsive SSRIs, Clomipramine Obsessive Depressed Antidepressants/Trazodone Inadequate response/side-effects Other drugs Cimetidine, Pindolol Inadequate response/side-effects Hormonal agents MPA***, CPA****, GnRh analogues stigma of chemical castration) * Combine with behavioral management ** Selective Serotonin Reuptake Inhibitors *** Medroxyprogesterone Acetate **** Cyproterone Acetate Figure 1.
