Study Notes
Changes in Intensity: Hyper- and Hypo-aesthesia
- Hyperaesthesia: increased intensity of sensations due to intense emotions or lowered physiological threshold
- Examples of hyperaesthesia: seeing roof tiles as brilliant flaming red, hearing door closing as a clap of thunder
- Associated conditions: anxiety and depressive disorders, hangover from alcohol, migraine
- Hyperacusis: increased sensitivity to noise, even day-to-day noises, causing discomfort
Factors Affecting Sensory Perception
- Emotional state: hypomanic, epileptic aura, or under the influence of LSD can lead to bright and intense colours
- Normal emotions: intense emotions like religious fervour or romantic love can also cause increased sensory perception
Hypo-aesthesia
- Hypoacusis: decreased sensitivity to sound, often seen in delirium
- Causes of hypoacusis: raised threshold for all sensations, defect of attention, and attentional deficits
- Importance of speaking to delirious patients: slowly and louder than usual to compensate for hypoacusis
- Associated disorders: depression, attention-deficit disorder
- Other affected senses: visual and gustatory sensations may also be lowered in depression
