THINKING PROCESSES
? Abstract thinking: thinker can conceptualize or generalize, understanding that each concept can have
multiple meanings.
? Concrete thinking: thinking is limited to what's in front of the face, and the here and now.
Freud's Primary and Secondary thinking processes:

--- Content provided by FirstRanker.com ---

Primary Process:
? Drive-dominated, prelogical, preverbal, imaginative thinking
? Consists of those mental processes which are directly related to functions of the primitive life forces
associated with the Id
? The Id has no contact with reality and works on the Pleasure Principle.

--- Content provided by FirstRanker.com ---

? Primary Process is characteristic of unconscious mental activity; marked by unorganized, non-logical
thinking and by the tendency to seek immediate discharge and gratification of instinctual urges.
? When Primary Process plays a significant role in a person's thinking he is incapable of being inner-directed.
Secondary Process:
? Reality oriented, goal-directed, logically ordered, rational, concrete and/or abstract conceptual thinking

--- Content provided by FirstRanker.com ---

? Consists of those mental processes which are directly related to learned and acquired functions of the Ego
? Characteristic of conscious and preconscious mental activity; marked by logical thinking and by the
tendency to delay gratification by regulation of the discharge of instinctual demands.

Diagnostic Criteria for Delirium, Not Induced by Alcohol and Other Psychoactive Substances
A. There is clouding of consciousness, i.e., reduced clarity of awareness of the environment, with reduced

--- Content provided by FirstRanker.com ---

ability to focus, sustain, or shift attention.
B. Disturbance of cognition is manifest by both:
1. impairment of immediate recall and recent memory, with relatively intact remote memory;
2. disorientation in time, place, or person.
C. At least one of the following psychomotor disturbances is present:

--- Content provided by FirstRanker.com ---

1. rapid, unpredictable shifts from hypoactivity to hyperactivity;
2. increased reaction time;
3. increased or decreased flow of speech;
4. enhanced startle reaction.
D. There is disturbance of sleep or of the sleep-wake cycle, manifest by at least one of the following:

--- Content provided by FirstRanker.com ---

1. insomnia, which in severe cases may involve total sleep loss, with or without daytime drowsiness, or
reversal of the sleep-wake cycle;
2. nocturnal worsening of symptoms;
3. disturbing dreams and nightmares, which may continue as hallucinations or illusions after awakening.
E. Symptoms have rapid onset and show fluctuations over the course of the day.

--- Content provided by FirstRanker.com ---

F. There is objective evidence from history, physical and neurological examination, or laboratory tests of an
underlying cerebral or systemic disease (other than psychoactive substance-related) that can be presumed
to be responsible for the clinical manifestations in Criteria A to D.
Comments

o
Neuroleptic sensitivity syndrome - marked sensitivity typical doses of antipsychotic drugs (resulting in
severe extrapyramidal side-effects with use of antipsychotics).
Antipsychotics (Haloperidol and Risperidone) use to treat disruptive behavior in dementia has decreased
markedly due to possible association with increased mortality

--- Content provided by FirstRanker.com ---

Antipsychotics should be avoided if Lewy body dementia is suspected
ORGANIC HALLUCINOSIS
? Presence of persistent or recurrent hallucinations due to an underlying organic cause.
? Usually visual (most common) or auditory in nature.
Etiology

--- Content provided by FirstRanker.com ---

? Drugs: Hallucinogens (LSD, psilocybin, mescaline), cocaine, cannabis, phencyclidine etc.

Other forms of depression
Atypical depression ? a term that has been applied to a variety of presentations, but particularly to patients
who present with mild to moderate depression, some mood reactivity, reverse diurnal variation in mood (i.e.
worse in the evening), overeating, hypersomnia and fatigue.

--- Content provided by FirstRanker.com ---

Dysthymia ? depressive symptoms which are insufficient to meet the criteria for a clinical depression. The
patient's symptoms are present for 2 or more years. Can be associated with other psychiatric conditions
such as borderline personality disorder. Sufferers often go on to develop more serious mood disorder.
Cyclothymic disorder ? chronic mood fluctuations over at least 2 years with episodes of elation and of
depression insufficient to meet the criteria for a hypomanic depressive episode.

--- Content provided by FirstRanker.com ---

Masked depression ? a state in which depressed mood is not particularly prominent, but other features of
depressive disorder are present, e.g. sleep disturbance, diurnal mood variation, depressive cognitions.
Mild depressive disorders ? milder forms of the symptoms of depression, with less disruption to social
functioning. These are likely to be accompanied by prominent anxiety, phobic or obsessional symptoms.
Recurrent brief depressive disorder ? lasts for <2 weeks, usually around 2-3 days. Occurs around once per

month, with complete recovery between episodes. The actual symptoms collectively may fulfil the criteria
for mild, moderate or severe depression, but the difference is in the duration of the episode.
SAD ? a temporal relationship between the season of the year and the onset of depression. The depression
starts in autumn/winter and resolves in spring/ summer. There may be symptoms of depression and
additional atypical biological features such as carbohydrate craving, fatigue and hypersomnia.

Two phases:
1.
D-Sleep (desynchronized or dreaming sleep) OR REM-sleep (rapid eye movement sleep), active sleep or
paradoxical sleep.
2.

--- Content provided by FirstRanker.com ---

S-Sleep (synchronized sleep), or NREM ? sleep (non-REM sleep), quiet sleep, or orthodox sleep. S-sleep or
NREM-sleep is further divided into four stages, 1 to 4.
The EEG recording
? During the awake state shows alpha waves of 8-12 cycles/sec. frequency
? The onset of sleep is characterized by a disappearance of the alpha ? activity.

? NREM ?sleep
o
Stage 1: first and the lightest stage of sleep, absence of alpha-waves, and low voltage, predominantly
theta activity.
o

--- Content provided by FirstRanker.com ---

Stage 2: characterized by two typical EEG changes:
Sleep spindles: Regular spindle shaped waves of 13-15 cycles/sec. frequency, lasting 0.5-2.0
seconds, with a characteristic waxing and waning amplitude.
K-complexes: High voltage spikes present intermittently.
o

--- Content provided by FirstRanker.com ---

Stage 3: appearance of high voltage, 751.1V, 6-waves of 0.5-3.0 cycles/sec.
o
Stage 4: predominant -activity

The important time periods of the various sleep stages
? In an 8 hour sleep, usually 6-61/2 hours are spent in NREM ?sleep & 11/2 ? 2 hours in REM-sleep.

--- Content provided by FirstRanker.com ---

? Out of 6-6112 hours NREM-sleep period, only about 70-80 minutes are spent in Stage 4 sleep.
? The maximum Stage 4 sleep occurs in the first one-third of the night
? In the later part, the REM-sleep follows the Stage 3 NREM ?sleep directly.
? REM-sleep occurs maximally in the last one-third of the night.
? REM-sleep occurs regularly after every 90-100 mins, with progressive lengthening of each REM period.

--- Content provided by FirstRanker.com ---

? The first REM period typically lasts for less than 10 minutes.
? Usually, there are 4-5 REM periods in the whole night of sleep.
? The usual sleep duration in newborn children is 16-18 hours/day, with nearly 8-10 hours spent in the REM-
sleep.
