Synonyms and keywords: Insomnia disorder
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
Insomnia has also been classified by the International Classification of Sleep Disorder, 3rd Edition into[2]:
- Chronic Insomnia Disorder
- Short-term Insomnia Disorder
- Other Insomnia Disorder
Causes
Symptoms may include waking up a night, waking up too early, difficulty falling asleep at night, fatigue, impaired concentration and recall, irritability, Constant worries about sleep, Depression, anxiety and increased accidents or error prone.
Common causes include[3]:
- Excess consumption of caffeine, nicotine and alcohol
- Medication induced
- Prescription drugs
- Over the counter drugs
- Bad sleep habits: Using bed for work, eating or any other leisure, disrupted bedtime schedule, frequent naps, stimulating activities before bed, disturbed sleep environment.Use of electronic gadgets just before bed can also interfere with the sleep cycle.
- Eating too much before bedtime causing GI discomfort or heartburn while lying down.
- Jet lags, Constant change in shifts, working too late or an early shift can disrupt the body's circadian rhythm
- Trauma and Stressful life experiences
- Depression or Anxiety or PTSD
- Medical conditions like GERD, chronic pain, cancer, cardiac diseases, asthma, overactive thyroid.
- Sleep-related disorders like Restless leg syndrome and sleep apnea
