Geriatric considerations w/ SUD
When assessing and treating older adults, clinicians not only need to take the above factors into account but also need to consider the potential interaction between alcohol and both prescribed and over-the-counter medications, especially psychoactive medications such as benzodiazepines, barbiturates, and antidepressants.
The Alcohol Use Disorders Identification Test (AUDIT) and the CAGE often a`re used to screen for at-risk substance use or misuse among older adults
Alcohol problems are common among older adults.
The use of pharmaceutical drugs is prevalent in older adulthood, and the risk of misusing prescription and over-the-counter medications, which include substances such as sedatives/hypnotics, narcotic and nonnarcotic analgesics, diet aids, and decongestants, also increases with age.
Incidentally, benzodiazepines also tend to be one of the most inappropriately prescribed psychotherapeutic medications among older adults
63
Screening tool for alcohol use disorder in geriatric population
The Alcohol Use Disorders Identification Test (AUDIT) and the CAGE often are used to screen for at-risk substance use or misuse among older adults
64
Tx considerations in geriatric population
Clinicians should be cautious when prescribing or recommending a treatment, take both risks and benefits into account when determining a treatment plan, and clearly communicate guidelines for appropriate use to patients.
Clinicians also should carefully consider discontinuing medications that do not prove effective
Illicit drug use among older adults is rare.
Thus, rates of illicit substance use and abuse among older adults will likely continue to rise in the next several decades because of the aging of the baby boom cohort.
When assessing and treating older adults, clinicians not only need to take the above factors into account but also need to consider the ******potential interaction between alcohol and both prescribed and over-the-counter medications, especially psychoactive medications such as benzodiazepines, barbiturates, and antidepressants.******

Perinatal (Anoxia, prematurity, birth trauma) and Postnatal (malnutrition,
toxin exposure, trauma)
Management: Behavioral Therapy
****Caution with patients with IDD as they may not be able to self-report drug-related problems.

* ****Monitor Height, weight, BP, CBC w/ diff; Pulse quarterly (Height and weight d/t risk of growth restriction)***
* In healthy individuals, it is not necessary to obtain an EKG prior to initiating a stimulant
* Prescription Monitoring Program should be checked
* Note: With stimulants, evidence of growth suppression is not clear, seems transient
and resolves in mid-adolescence
* Note: If a child is taking their medication twice daily (i.e. at home and school) and parents request to solely administer the medication= consider switching to an extended release form (e.g. Methylphenidate CD= extended release)

Mirtazapine (Remeron) cause sexual problems
* Desire (libido)
* Frequency of sexual activity
* Arousal (lubrication in females and erectile function in males)
* Orgasm (delayed orgasm and anorgasmia)
101
How to manage sexual SE from antidepressants
Watchful waiting; if sexual impairment persists:
* Decrease the dose of the SSRI within the therapeutic range.
* Switch to Bupropion (Wellbutrin)
* phosphodiesterase-5 inhibitor (ie sildenafil and tadalafil) cause the blood vessels to relax.
102

pharmacologic intervention, after non pharmacologic treatments have
been tried, what med is first line

General tx personality disorders
Personality disorders are generally very difficult to treat especially since few patients will acknowledge they need help
These disorders tend to be chronic and lifelong

General tx guidelines personality disorders
* First-line treatment for personality disorders is psychotherapy.
* Symptom-focused, medication treatment of personality disorders is
generally considered to be an adjunct to psychotherapy.
* Avoid prescribing medications that can be fatal in overdose, such as
tricyclic antidepressants.
* Avoid prescribing medications that can induce physiological dependence and tolerance, including benzodiazepines.
* Avoid changing medication each time there is a crisis or change in
mood symptoms, which may occur frequently and suddenly, and also
remit suddenly in some people with personality disorders.

waxes and wanes in relationship to life circumstances.

with doses used in the treatment of schizophrenia (e.g. Abilify,
Risperdal, Seroquel)

127
SE stimulants
Side effects: GI upset, anorexia, weight loss, BP changes, ↑ HR, Growth suppression(rare),sleep disturbance, jitteriness, headaches, dizziness, mood lability -irritability, psychosis (rare), social withdrawal

FDA approved for children 3+
Side effect: Loss of appetite, headaches, ↑BP; stomachaches, nausea, weight loss, insomnia, anticholinergic, tics/repetitive movements, psychosis
133

134
When to consider non stimulant meds for ADHD
Stimulants are not working well to control ADHD symptoms
Stimulants cause too many side effects
The child or teen has problems with substance abuse

154
Difference between Lewy body dementia & parkinsons demetia
both irreversible, the main difference between the two is the sequence of events
In Parkinson’s disease, the symptoms of parkinsonism usually come first followed by dementia. On the other hand, in Lewy body dementia, dementia comes first, followed by parkinsonism and individuals are “dopamine-sensitive”, meaning it can cause them to hallucinate, become agitated, and be confused.
