Overview
Historical Perspective
Pathophysiology
It is thought that insomnia is mediated by:
- Molecular Mechanism
- Hormones causing wakefulnessn: Catecholamine, Histamine, Orexin
- Hormones promoting sleep: Adenosine, serotonin, GABA, melatonin, Prostaglandin D2
- Hyperarousal model
- Cognitive
- Physiologic
- Cortical
- Genetic: ApoE4, PER3, 5HTTLPR, Single Nucleotide Polymorphism, CLOCK gene, HLA DQI*002
- Sleep switch Model (Orexin mediated)
- Sleep promoting areas:Ventrolateral Preoptic and Median preoptic Nucleus
- Wake promoting areas: Tuberomammillary nucleus, dorsal raphe, Locus coeruleus
- Cognitive and Behavioural Model
- Precipitating factors
- Predisposing factors
- Perpetuating factors
Classification
Insomnia has been classified by the International Classification of Sleep Disorders, 2nd Edition into 11 categories[1]:
- Psychophysiologic insomnia (primary insomnia)
- Adjustment insomnia (acute insomnia)
- Paradoxical insomnia
- Behavioral insomnia of childhood
- Primary sleep disorders causing insomnia
- Idiopathic insomnia
- Inadequate sleep hygiene
- Insomnia due to mental disorder
- Insomnia due to drug or substance abuse
- Insomnia due to a medical condition
- Insomnia not due to a substance or known physiologic condition, unspecified
