Hyperosmia is an increased olfactory acuity (heightened sense of smell), usually caused by a lower threshold for odor. [1] This perceptual disorder arises when there is an abnormally increased signal at any point between the olfactory receptors and the olfactory cortex. The causes of hyperosmia may be genetic, hormonal, environmental or the ...
Hyperacusis is an increased sensitivity to sound and a low tolerance for environmental noise. Definitions of hyperacusis can vary significantly; it often revolves around damage to or dysfunction of the stapes bone, stapedius muscle or tensor tympani (eardrum). It is often categorized into four subtypes: loudness, pain (also called noxacusis ...
Hyperesthesia is a condition that involves an abnormal increase in sensitivity to stimuli of the senses. Stimuli of the senses can include sound that one hears, foods that one tastes, textures that one feels, and so forth. Increased touch sensitivity is referred to as "tactile hyperesthesia", and increased sound sensitivity is called "auditory ...
Sensory integration difficulties or sensory processing disorder (SPD) are characterized by persistent challenges with neurological processing of sensory stimuli that interfere with a person's ability to participate in everyday life. Such challenges can appear in one or several sensory systems of the somatosensory system, vestibular system ...
Hearing: loud noise, or sound from multiple sources, such as several people talking at once. Sight: crowded or cluttered spaces, bright lights, strobing lights, or environments with much movement such as crowds or frequent scene changes on television. Smell and taste: strong aromas or spicy foods.

[2] The sense of smell has many functions, including detecting desirable foods, hazards, and pheromones, and plays a role in taste.
t. e. Sensory processing sensitivity (SPS) is a temperamental or personality trait involving "an increased sensitivity of the central nervous system and a deeper cognitive processing of physical, social, and emotional stimuli". [2] The trait is characterized by "a tendency to 'pause to check' in novel situations, greater sensitivity to subtle ...
Hypersensitivity (also called hypersensitivity reaction or intolerance) is an abnormal physiological condition in which there is an undesirable and adverse immune response to an antigen. [ 1 ][ 2 ] It is an abnormality in the immune system that causes immune diseases including allergies and autoimmunity. It is caused by many types of particles ...
