Substance Abuse, Human Sexuality and Sleep Flashcards
Drugs working in nucleus accumbens
- Amphetamines
- Cocaine
- Opiates
- TCH
- PCP
- Nicotine
- Ketamine
Sexual Identity
Based on person’s secondary sexual characteristics
Stage 1 EEG waves
Theta waves (3-7 cps)
Substance Abuse Diagnosis
One or more of the following in 1 year:
- Failure to fulfill responsibilities at work, school or home
- Use in physically hazardous situations (driving while intoxicated)
- Legal problems during the time of use
- Continued used despite recurrent social or interpersonal problems secondary to the effects of such use
Benzodiazepines Withdrawal specific findings and Treatment
- Sleep disturbance
- Depression and rebound anxiety
- Rx: supportive
Circadian rhythm sleep disorders Treatment
- Sleep hygiene
- Dark therapy: blue blocking goggles (blocks blue and bluegreen wavelength) during evening hours so production of melatonin is not reduced or eliminated
- Modafinil
- Melatonin may be useful if given 5 and a half hours before the desired bed time
- Tasimelteon (melatonin agonist) for treatment of just non-24-hour sleep-wake disorder in totally blind people
- Sleep phase chronotherapy
Alcoholism treatment
Important notes
- Most successful way to get person to treatment is to be referred by employer
- The 12-step program (Grassroots movement)
- Spiritual program
- Al-Anon program for family and friends: deals with codependence and enabling behavior
- Disulfiram which interferes with aldehyde dehydrogenase and produces symptoms of nausea, chest pain, hyperventilation, tachycardia and vomiting. It should be used with psychotherapy
- Naltrexone: reduces cravings
- Acamprosate
Consequences of sleep deprivation
- Decreased lymphocyte levels
- Cortisol level rises
- Blood pressure rises
- Glucose tolerance is reduced
- Greater amygdala activation
- Lower prefrontal cortical activity
- Increased negative mood
Melatonin and Sleeping
- It’s not related to sleep but rather to feelings of sleepiness
- Produced by pineal gland and directly in the retinas of the eyes
- Release inhibited by daylight, while at night time levels rise dramatically
- Responsible for “jet lag” and seasonal affective disorder (SAD)
- Adjust it with bright light therapy not pills
Heroine addiction risks and treatment
- Users at increased risk of hepatitis, HIV, abscesses, bacteremia, right-heart endocarditis
- Rx:
- Methadone: for detoxification or long-term maintenance
- Naloxone+buprenorphine: withdrawal symptoms occur only if injected (lower abuse potential)
- Naltrexone: relapse prevention once detoxified
Barbiturates Withdrawal specific findings and Treatment
- Autonomic hyperactivity
- Hallucinations
- Grand mal seizures
- Delirium
- Life-threatening cardiovascular collapse and death
- Rx: supportive
Physiology of substance abuse
Mesolimbic pathway: stimulus (food, drugs, sex, kindness) —-> cerebral cortex —-> ventral tegmental area —-> nucleus accumbens (Dopamine which increases desire for stimulus and Serotonin which gives body the impression of satisfaction so cravings are reduced)
CNS Stimulants drugs
- Amphetamines
- Cocaine
- Caffeine
- Nicotine
Sleep Apnea consequences
- High risk of death during sleep, development of severe nocturnal hypoxemia, pulmonary and systemic hypertension (elevated diastolic pressure)
- Nocturnal cardiac arrhythmias (life-threatening)

Awake EEG waves
Low voltage random fast beta waves
Sexual Desire Disorders
- Hypoactive: deficiency or absence of fantasies or desires, 20% of population, more common in women. Causes: low testosterone in men, CNS depressants, common post-surgery, depression, marital discord, and oral contraceptives which depress libido
- Sexual aversion: aversion to all sexual contact
Colleague physician with substance abuse (steps of management)
1- Get the colleague to suspend patient contact
2- You must report it to hospital administration and the State Board (according to your position)
3- Ideally, get the colleague into treatment
Stage 2 EEG waves
Sleep spindles (12-14 cps) and K complexes
Sleep Facts
- Circadian rhythm which is regulated by superchiasmatic nucleus (SCN)
- Most NREM stages 3 and 4 occur during the first half of night
- Stage 3 and 4 are known as delta sleep or slow-wave sleep
- Most REM occurs during the last half of night. REM gets progressively longer as night goes on. REM is an example of ultradian rhythm
- Average adult spends most sleep time in stage 2, and least in stage 1. Most commonly wake out of REM or stage 2
- Sleep latency 5-15 minutes
- REM latency 90 minutes
Caffeine Psychopharmacology
Antagonist of adenosine receptors, increased cAMP in neurons that have adenosine receptors
Sudden Infant Death Syndrome (SIDS)
- Maternal smoking and families where someone smokes are high risk
- 5-HT levels 25% below normal
- 50% reduction if baby placed on back rather than on stomach
Phencyclidine (PCP, angel dust) Psychopharmacology
Antagonist of N-methyl D-aspartate glutamate receptors, prevents influx of calcium ions, activates dopaminergic neurons
Delta sleep changes
Increase after exercise and seems to be the result of raised cerebral temperature
Lysergic acid diethylamide (LCD), mescaline and ketamine Withdrawal specific findings and Treatment
None
Female Sexual Arousal Disorder
- Women unable to achieve adequate vaginal lubrication
- May be hormonally related: many women report peak sexual desire just prior to menses
- Anti-histamines and anti-cholinergics cause decrease in vaginal lubrication
Notes on Diagnosis and Treatment of Substance abuse
- Substance use is often denied or under-reported, so seek out collateral info from family and friends
- Check urine and blood toxicology screens, LFTs and serum EtOH level
- Detoxification: usually 5 to 10 days in hospital settings to assure safe detoxification
- Rehabilitation: usually 28 days or more, with focus on relapse prevention techniques
- Other Rx is according to the type of substance abused
