IN THIS SYNDROME THE START OF K COMPLEXES AND SPINDLES ARE DELAYED. IN SOME PATIENTS THEY ARE NOT SEEN UNTILL THE AGES OF 3-5.
|
RETT SYNDROME
|
|
|
THESE SYMPTOMS ARE INDICATED IN WHAT SYNDROME.
FLU LIKE SYMPTONS EXCESSIVE HYPERSOMNOLENCE HYPERSEXUAL TENDENCIES |
KLEIN-LEVIN SYNDROME

|
|
THIS IS THE MEASURING UNIT OF FLOW?
|
VOLTAGE
VOLTAGE MUST ALWAYS BE MEASURED ACROSS TWO POINTS. WE ARE ACTUALLY MEASURING THE DIFFERNECE IN ENERGY BETWEEN THE TWO POINTS. |
|
|
AMPLIFIERS FUNCTION BY...
|
DIFFERENTIAL AMPLIFIERS ARE USED FOR MOST LEADS, THEY REDUCE UNWANTED NOISE. THE AMPLIFIER FUNCTIONS BY RECIEVING 2 DIFFERENT LEADS.
1 SEEKING G1 2 REFRENCE G2 THE AMPLIFIER COMPARES THE SAME DATA-NO SIGNAL-NO DATA |
|
|
SENSITIVITY
|
THE DEGREE OF PEN DEFLECTION ON THE RECORDER THAT RESULTS FROM A GIVEN STRENGTH OF ELECTRICAL SIGNAL THAT IS PRESENTED TO THE RECORDER. SENSITIVITY IS EXPRESSED IN uV/cm (MICROVOLTS PER CENTIMETER)
|
|
|
TIME CONSTANT
|
THE TIME IS TAKES FOR THE PEN ON THE RECORDER TO RISE TO PEAK OF THE WAVE DURING A CALIBRATION SIGNAL AND FALL TO THE BASE LINE.
RISE TIEM CONSTANT- TIME IT TAKES THE PENT TO REACH 67% MAXIUM PEN DEFLECTION. FAL TIME CONSTANT- TIME IT TAKES THE PEN TO FALL TO 37% OF THE FULL AMPLITUDE. ON OUR MONTAGE THE FALL TIME CONSTANT IS USED. |
|
|
WHAT IS THE MAIN DIFFERENCES BETWEEN A DELTA WAVE AND A K COMPLEX?
|
DELTA WAVES MUST BE 75 MICROVOLTS IN AMPLITUDE. DELTA WAVES ARE UNIPHASIC.
K COMPLEXES ARE BIPHASIC AND HAVE NO AMPLITUDE CRITERIA. |
|
|
ALCOHOL MAY HAVE WHAT EFFECTS ON SLEEP?
|
LOW LEVELS CAN INDUCE SLEEP.
HIGH LEVELS CAN DECREASE REM. CHRONIC USE-SLOW WAVES DISAPPEAR. PT MAY COMPLAIN OF INSOMNIA AND SLEEP FRAGMENTATION. WITHDRAWLS FORM CHORNIC USE RESULTS IN DECREASED SLOW WAVE AND REM, MAY PERSIST SEVERAL FOR SEVERAL MONTHS AFTER USAGE STOPPED. |
|
|
WHAT DRUGS INCREASE STAGE II AND SUPPRESS K COMPLEXES?
|
BENZODIZEPINES INCREASE STAGE II WHILE SUPPRESSING K COMPLEXES . XANAX MAY IN CREASE DENSITY AND LENGTH OF SPINDLES.
CHRONIC USE DECREASES REM. ABRUPT DISCONTINUING OF MEDS MAY CAUSE REM REBOUND. EX. OF BENZODIZEPINES XANAX, ATIVAN, VALIUM, LIBRIUM. |
|
|
WHAT EFFECTS DO NREM AND REM HAVE ON BRAIN TEMP?
|
TEMP IN NREM DECREASE, TEMP IN REM INCREASE.

CAFFEINE MAY HAVE WHAT EFFECTS ON SLEEP?
|
CAFFEINE IS A STIMULANT.
DELAYS SLEEP ONSET. MAY DECREASE DURATION OF REM SLEEP. |
|
|
THEOPHYLLINE HAS A STIMULANT EFFECT, PT'S USING THIS DRUG MAY COMPLIAN OF...

PARALYSIS OCCURING AT SLEEP ONSET?
|
HYPNAGOGIC PARALYSIS
|
|
|
NARCOTICS HAVE WHAT EFFECTS ON SLEEP STAGING?
|
DECREASE REM

SLEEP PARALYSIS OCCURING DURING AWAKENING FROM SLEEP?
|
HYPNOPOMPIC SLEEP PARALYSIS

|
|
ANTIDEPRESSANTS HAVE WHAT EFFECT ON SLEEP STAGES?
|
ABRUPT WITHDRAWL MAY CAUSE REM REBOUND.
TCA-TRICYCLIC ANITIDEPRESSANTS(EX. AMPITRYPTILINE) HAVE SEDATING PROPERTIES. DECREASES SLEEP LATENCY, INCREASES SLEEP EFFICIENCY. SSRI- SELECTIVE SERATONIN REUPTAKE INHIBITORS(EX. PROZAC, ZOLOFT) DECREASE REM WELLBUTRIN MAY CAUSE INSOMNIA, PT'S NEED TO TAKE MED. EARLIER IN DAY. |

|
|
EXAMPLES OF POOR SLEEP HYGEINE.
|
EXPOSURE TO BRIGHT LIGHTS BEFORE BED.
EXCERCISING BEFORE BED. HOT BATH BEFORE BED. INCONSISTENT SLEEP PATTERS. |
|
|
A GENETIC DISORDER CHARACTERIZED BY SLEEPINESS, CATAPLEXY AND HYPNAGOGIC HALLUCINATIONS.

NARCOLEPSY
|
|
|
WHAT AGE IS NARCOLEPSY USUALLY DIAGNOSISED?
|
14-18
|
|
|
DRUGS USED TO TREAT NARCOLEPSY?
|
AMPHETAMINES, TRYCYCLIC ANITIDEPRESSANTS.
RITALIN, DEXADRINE, MODAFINIL. |
|
|
CATAPLEXY
|
TRACE LIKE STATE. SUDDEN LOSS OF MUSCLE TONE CAUSED BY THE INTRUSION OF REM INTO WAKE.
