Anosmia is the inability to perceive odor, or in other words a lack of functioning olfaction.Many patients may experience unilateral or bilateral anosmia. A temporary loss of smell can be caused by a blocked nose or infection. In contrast, a permanent loss of smell may be caused by death of olfactory receptor neurons in the nose or by brain injury in which there is damage to the
Sensory processing disorder is present in many people with dyspraxia, autism spectrum disorder, and attention deficit hyperactivity disorder (ADHD). Individuals with SPD may inadequately process visual , auditory , olfactory (smell), gustatory (taste), tactile (touch), vestibular (balance), proprioception (body awareness), and interoception ...

Dysgeusia often occurs for unknown reasons. A wide range of miscellaneous factors may contribute to this taste disorder, such as gastric reflux, lead poisoning, and diabetes mellitus. [21] A minority of pine nuts can apparently cause taste disturbances, for reasons which are not entirely proven. Certain pesticides can have damaging effects on ...
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
It is usually associated with brain injury or neurological illness, particularly after damage to the occipitotemporal border, which is part of the ventral stream. [2] Agnosia only affects a single modality, [3] such as vision or hearing. [4] More recently, a top-down interruption is considered to cause the disturbance of handling perceptual ...
Damage in this way is caused by a variety of different illnesses and diseases. A few examples of the most common illnesses and diseases that can cause hypoesthesia as a side effect are as follows: Decompression sickness; Trigeminal schwannoma; Rhombencephalitis; Intradural extramedullary tuberculoma of the spinal cord; Cutaneous sensory ...
Nociceptors respond to potentially damaging stimuli by sending signals to the spinal cord and brain. This process, called nociception, usually causes the perception of pain. [16] They are found in internal organs, as well as on the surface of the body. Nociceptors detect different kinds of damaging stimuli or actual damage.
