disorders F40 – phobic anxiety disorders F 41 – other anxiety disorders F 42 – Obsessive compulsive disorder F 43 – Reaction to severe stress and adjustment

Psychopathology Disturbances in serotonin,
norepinephrine and gamma aminobutyric acid (GABA) appear to be most significant.
Serotonin is thought to be decreased and norepinephrne is thought to be increased in anxiety disorders.
GABA is decreased in anxiety disorders , allowingfor increased cellular excitability.

Etiological factors Psychoanalytic theories Freud proposed that anxiety is a signal
to the ego to take defensive action against the “pressure” from within. If repression is unsuccessful as a defense, other defense mechanisms may result in symptom formation

Generalized Anxiety Disorders (GAD) It is an anxiety disorder that is
characterized by excessive, uncontrollable and often irrational worry about everyday things that is disproportionate to the actual source of worry
It is a common chronic disorder characterized by long lasting anxiety that is not focused on any one subject or situation.

Biological theories 1. Autonomic nervous system James Lange theory states that
subjective anxiety is a response to peripheral phenomena. Stimulation of autonomic nervous system causes cardio vascular, respiratory and GI symptoms

2. Norepinephrine (NE) Studies have found that, in patients with
panic disorder, - adrenergic agonists (isoproterenol) and - adrenergic antagonists (yohimbine) can produce frequent and severe panic attacks, conversely clonodine, an adrenergic agonist, reduces anxiety symptoms in some experimental and therapeutic situations

Environmental factors Trauma, stressful events, changing jobs
or schools GAD s worse during the period of stress Use and withdrawal from addictive
substances, alcohol, caffeine, nicotine etc can worsen anxiety

Panic disorder A sudden overwhelming feeling of terror
or impending doom. This severe form of emotional anxiety is usually accompanied by behavioral, cognitive and physiological signs and symptoms considered to be outside the expected range of normalcy
![Page 20: Neurotic disorders](https://reader035.vdocument.in/reader035/viewer/2022062222/568164d9550346895dd7245d/html5/thumbnails/20.jpg)
Classification F41.0 – panic disorder F41.1 – Generalized Anxiety Disorder F 41.2 – Mixed anxiety and depressive
disorder F41.9 – other specified anxiety disorders
![Page 21: Neurotic disorders](https://reader035.vdocument.in/reader035/viewer/2022062222/568164d9550346895dd7245d/html5/thumbnails/21.jpg)
Epidemiology Lifetime prevalence estimates range
from 1.5 – 5% for panic disorder and 3- 5.6% for panic attacks
Women are more likely to be affected than men by a 2-3 fold factor
Highest incidence is in late adolescence and second peak in mid 30s.
![Page 22: Neurotic disorders](https://reader035.vdocument.in/reader035/viewer/2022062222/568164d9550346895dd7245d/html5/thumbnails/22.jpg)
Causes Genetic factors (the concordance rate in
monozygotic twins of patients with panic disorder is 80%)
Biochemical factors (reduction in GABA activity in brain)
Malfunctioning of brain structure such as amyldala and hormonal/ adrenaline glands.
Co morbid condition with heridity disorders , such as bipolar disorder and genetic predisposition to alcoholism
![Page 23: Neurotic disorders](https://reader035.vdocument.in/reader035/viewer/2022062222/568164d9550346895dd7245d/html5/thumbnails/23.jpg)
Medical conditions like hypoglycemia, hyperthyroidism, mitral valve prolapse, labirinthitis and pheochromocytoma can aggravate panic disorder
Stressful life events, life transitions and environment play a role in the onset of panic disorder.

psychopathology Serotonergic model suggests an
exaggerated or inefficient post synaptic receptor response to synaptic serotonin
Catecholamine model postulates increased sensitivity to or improper processing of adrenergic CNS discharge, with potential hypersensitivity of presynaptic alpha-2 receptors
![Page 25: Neurotic disorders](https://reader035.vdocument.in/reader035/viewer/2022062222/568164d9550346895dd7245d/html5/thumbnails/25.jpg)
Lactate model focuses on symptom production by postulated aberrant metabolic activity induced by lactate.
GABA model postulates decreased inhibitory receptor sensitivity, with a resultant excitatory effect
Neuroanatomic model suggests panic attacks are mediated by a fear network in the brain that involves amygdala, hypothalamus and brainstem centers.
