Psychopathological phenomena, symptoms of abnormal states of mind
Psychiatry (from the Greek words
"psyche" - the soul, "iatreia" - treatment) is a branch of medicine concerned with the study, diagnosis, treatment and prevention of mental disorders.
Difference between psychiatry and psychology?
- psychiatrist has attended medical school and is a physician and therefore holds an M.D.
- in residency received specialised training in the
field of psychiatry
- psychiatry tends to focus mainly on the use of medications for treatment
When you speak to God it's called praying; but when God speaks to you it's called schizophrenia.

Classification of mental disorders on the basis of aetiology and pathogenesis
1) endogenous disorders (schizophrenia, bipolar affective disorder and genuine epilepsy) caused by internal mechanisms, the nature of which isn't yet quite clear; these are disorders with he reditary predisposition.
2) exogenous disorders, caused by ex ternal reasons: infection, intoxication, head injury, etc.;
3) psychogenous disorders are caused by psychological trauma (posttraumatic stress syndrome) and other psychological factors (adjustment dis orders, behavioural disorders, neuroses, etc.).
Tasks psychiatry to study the aetiology and pathogenesis of mental disorders;
to carry out their classification;
to investigate the epidemiology of mental disturbances;
to study the symptoms and signs, as well as syndromes and the clinical course of different mental disorders;
to develop find practice effective methods of their diagnosing;
to work out and use efficient treatment methods;
to develop a network of mental health services for the population;
to develop a system for the prevention of mental disorders.
History of development of psychiatry
the first period (pre-scientific), characterised by primitive religious understanding of the mentally ill people's abnormal behaviour;
the secend period of ancient antique medicine, a more progressive period, when the first attempts at organising mental health treatment were made;
the third period, corresponding to the Middle Ages, was in general a period or regress, when psychiatry returned to its prescientific period (theological scholastics);
the fourth period, from the beginning of the XVIII to the beginning of XIX century was the stage of formation of psychiatry part of the medical science;
the fifth period was the epoch of E. Krepellin's nosological psychiatry. The creation of a nosological classification of mental disorders was the main outcome of this stage;
the sixth period, modern stage of development of psychiatry, formed in the XX century can be called the period of social psychiatry; it is characterised by wide development community, social forms of mental health services; somatological aspects of mental disorders got more attention.
FRAME OF PSYCHIATRY.
General psychopathology - studies the basic laws of an etiopathogenesis, clinic, diagnostics, therapy and prophylaxis of alienations.
Private psychiatry - studies separate mental diseases.
Age psychiatry. Organizational psychiatry. Judicial psychiatry - solves questions
of a sanity and capacity for acting. Psychopharmacotherapy - studying of
action on mentality of medicinal substances.
Social psychiatry.
Addictology - studies influence of the psychotropic substances on a condition of the person.
Trans-cultural psychiatry - is engaged in comparison of a mental pathology in the different countries, cultures.
Orthopsychiatry - surveys alienations from the point of view of different disciplines.
Biological psychiatry. Sexology. Suicidology. Military psychiatry - studies
posttraumatic stressful frustration, psychopathology a wartime.
Ecological psychiatry - studies influence of ecological factors on mentality.

Mental illness can occur when the brain (or part of the brain) is not working well or is working in the
wrong way.
Thinking
When the brain is not working properly, one or more of its 6 functions will be disrupted
PerceptionEmotion Signaling
Behavior
Physical
Symptoms can include
Sleep problemsExtreme emotional highs and lows
Thinking difficulties or problems focusing
attention
When these symptoms significantly disrupt a person’s life,
we say that the person has a
mental disorder or a mental illness.
Basic Terms in Psychiatry Psychiatry studies the causes of mental disorders,
gives their description, predicts their future course and outcome, looks for prevention of their appearance and presents the best ways of their treatment
Psychopathology describes symptoms of mental disorders
Special psychiatry is devoted to individual mental diseases
General psychiatry studies psychopathological phenomena, symptoms of abnormal states of mind:
1. consciousness 5. mood (emotions)2. perception 6. intelligence3. thinking7. motor4. memory 8. personality
Disorders of Consciousness Consciousness is awareness of the self
and the environment Disorders of consciousness:
• qualitative• quantitative
short-term long-term
Hypnosis – artificially incited change of consciousness
Syncope – short-term unconsciousness
Disorders of Consciousness Quantitative changes of consciousness mean
reduced vigility (alertness):• somnolence• sopor• coma
Qualitative changes of consciousness mean disturbed perception, thinking, affectivity, memory and consequent motor disorders:
• delirium (confusional state) – characterized by disorientation, distorted perception, enhanced suggestibility, misinterpretations and mood disorders
• obnubilation (twilight state) – starts and ends abruptly, amnesia is complete; the patient is disordered, his acting is aimless, sometimes aggressive, hard to understood
stuporous vigilambulant delirious Ganser sy
Disturbances of Perception Perception is a process of becoming aware of what
is presented through the sense organs Imagery means an experience within the mind,
usually without the sense of reality that is part of reality
Pseudoillusions – distorted perception of objects which may occur when the general level of sensory stimulation is reduced
Illusions are psychopathological phenomena; they appear mainly in conditions of qualitative disturbances of consciousness (missing insight)
Hallucination are percepts without any obvious stimulus to the sense organs; the patient is unable to distinguish it from reality
Disturbances of PerceptionHallucinations:
auditory (acousma) visual olfactory gustatory tactile (or deep somatic) extracampine, inadequate intrapsychic (belong rather to disturbances of thinking) hypnagogic and hypnopompic (hypnexagogic)
Pseudohallucinations - patient can distinguish them from reality
Disorders of Thinking Thinking
Cognitive functions
Disorders of thinking:• quantitative• qualitative
Quantitative Disorders of Thinking
Quantitative (formal) disorders of thinking: pressure of thought poverty of thought thought blocking flight of ideas perseveration loosening of associations word salad - incoherent thinking neologisms verbigeration
Qualitative Disorders of Thinking
Quantitative disorders of thought (content thought disorders):
Delusions: a)belief firmly held on inadequate grounds,b)not affected by rational argumentsc)not a conventional belief
Obsessions (obsessive thought) are recurrent persistent thoughts, impulses or images entering the mind despite the person's effort to exclude them. Obsessive phenomena in acting (usual as senseless rituals – cleaning, counting, dressing) are called compulsions.
Qualitative Disorders of Thinking
Division of delusions: according to onset
a)primary (delusion mood, perception)b)secondary (systematized)c)shared (folie a deux)
according to themea)paranoid (persecutory) - d. of reference, d. of jealousy, d. of
control, d. concerning possession of thoughtb)megalomanic (grandiose, expansive) – d. of power, worth,
noble origin, supernatural skills and strength, amorous d.c)depressive (micromanic, melancholic) – d. of guilt and
worthlessness, nihilistic d., hypochondriacal d.d)concerning the possession of thoughts

PSYCHOSIS
Psychoses are usually of the following two types:1. Manic-depressive Psychosis: It is expressed in
following two phases:(a) Mania phase: In this, the person is very active,
full of life, talking too much, mostly irreverent, the mood is elated and he does some action continuously. But he does not have touch with reality. He can commit any crime during this phase. Sleep is very less. Appetite is also less.

PSYCHOSIS
(b) Depressive phase: It is just the reverse of mania. The person is very sad, mood is depressed. The person sits alone and may speak very little. Touch with reality is not there. He may commit suicide. The motor functions are also quite depressed. A person suffering from manic depressive psychosis may fluctuate between the two phases of mania and depression. It may be possible that the person may be normal between the two phases of mania. This may be lucid interval and the person is completely responsible for his actions.

NEUROSIS
Depression: It is the reverse of anxiety. Here, a person would be aloof, sad and withdrawn. His motor activities would be quite less. He may have a low appetite and may not eat well. However, in chronic cases of depression, the person may keep on eating the whole day, while withdrawn at home and hence may gain weight. The following are the types of depression commonly seen:

A SUZY PRESENTATION
NEUROSIS
Reactive depression: It may be due to some event or situation like the death of spouse or a near one, failure in exam, love, etc. It usually remains there for sometime. Some form of reactive depression is seen in all individuals. Usually, with counseling and use of anti-depressive drugs, most come out of it.
1243/5/2015
A SUZY PRESENTATION
NEUROSIS
Endogenous depression: It is more serious as its etiology is not known and develops slowly. Early morning awakening, loss of appetite and mood depression are quite common. This depression may be associated with psychosis too, where it carries a bad prognosis. Usually with anti-depressive drugs, most of the individuals recover.
