Sensory Modulation Disorder Sensory Modulation Disorder. Sensory Modulation Disorder is one specific type of Sensory Processing Disorder (SPD). Sensory modulation refers specifically to the brain’s ability to respond appropriately to the sensory environment and to remain at the appropriate level of arousal or alertness.

- Sensory processing disorder is a condition that causes difficulties receiving and responding to information from the senses including vision, hearing, touch, smell, and taste. Sensory information is sensed by the person, however, the brain perceives and analyses the information in an unusual way. It may affect one sense alone or it may affect multiple senses. Someone with sensory processing disorder may have heightened or lowered sensitivity to stimuli such as tolerating light, being touched, sound, eye contact, and pain.

- Sensory nerve damage causes a variety of symptoms because sensory nerves have a broad range of functions. Larger sensory fibers enclosed in myelin register vibration, light touch, and position sense. Damage to large sensory fibers impairs touch, resulting in a general decrease in sensation.

Taste Disorders Most often, people are experiencing a loss of smell instead of a loss of taste. In other disorders of the chemical senses, an odor, a taste, or a flavor may be distorted. Dysgeusia [dis-GYOO-zee-a] is a condition in which a foul, salty, rancid, or metallic taste sensation persists in the mouth.

- Symptoms. Symptoms depend on which nerves are damaged and how they were damaged. Cranial nerve disorders can affect smell, taste, vision, sensation in the face, facial expression, hearing, balance, speech, swallowing, and muscles of the neck.For example, vision may be affected in various ways:ranial nerve disorders can affect smell, taste, vision, sensation in the face, facial expression, hearing, balance, speech, swallowing, and muscles of the neck.

Anxiety and physical illness Anxiety also plays a role in somatoform disorders, which are characterized by physical symptoms such as pain, nausea, weakness, or dizziness that have no apparent physical cause. Somatoform disorders include hypochondriasis, body dysmorphic disorder, pain disorder, and conversion disorder. Anxiety has now been implicated in several chronic physical illnesses, including heart disease, chronic respiratory disorders, and gastrointestinal conditions.

Somatoform Disorders As in other somatoform disorders, medical examinations and testing generally find no clear physical cause for the symptoms. Pain disorder and body dysmorphic disorder Two other kinds of somatoform disorders are pain disorder and body dysmorphic (dis-MOR-fik) disorder. Pain disorder is similar to somatization disorder, except that pain is the main symptom. The pain may be in one or several areas of the body, but it doesn't fit a pattern of any particular medical illness or injury, and diagnostic tests fail to show the presence of any disease.

Numbness (paresthesia and neuropathy) Abnormal sensations such as prickling, tingling, itching, burning or cold, skin crawling or impaired sensations–are all called parasthesia. These symptoms usually arise from nerve damage (neuropathy). Continued nerve damage can lead to numbness (lost of sensation) or paralysis (loss of movement and sensation). Paresthesia is one of the symptoms of Hypervitaminosis-D.

- Sensory symptoms are the next common type of aura and can occur on their own or follow the vision changes. The sensory part of the aura often begins with tingling of one limb or one side of the face that gradually moves to different parts of the body — like from the right shoulder down the to the right forearm.

Loss of Taste Sensation: Symptoms & Signs Loss of Taste Sensation Symptoms & Signs. Related. Symptoms & Signs. The sensations of taste and smell are related, so many disorders of the sense of taste are associated with a decreased sense of smell. These taste disorders can range from obstructions in or damage to the nose to damage to the brain and nervous system in general. The most common pure taste disorder is a phantom taste sensation; this is the perception of a bad taste in the mouth that does not go away.

- They are is not caused by damage or disease of the nervous system. Patients with functional sensory symptoms can experience the following: 1. A feeling of altered sensation down one side of the body (more commonly the left) - usually involving the face, arm or leg in various combinations. This is sometimes called 'hemisensory syndrome'. Facial sensory disturbance alone is quite common. 2. A feeling that a limb just doesn’t belong to them or ‘part of them’.

Sensory processing disorder Sensory-based motor disorder (SBMD) Sensory-based motor disorder shows motor output that is disorganized as a result of incorrect processing of sensory information affecting postural control challenges, resulting in postural disorder, or developmental coordination disorder. The SBMD subtypes are: Dyspraxia.

Sensory Processing Disorder Sensory processing disorder may affect one sense, like hearing, touch, or taste. Or it may affect multiple senses. And people can be over- or under-responsive to the things they have difficulties with. Like many illnesses, the symptoms of sensory processing disorder exist on a spectrum. In some children, for example, the sound of a leaf blower outside the window may cause them to vomit or dive under the table. They may scream when touched.

- 14.1 Measures of Visual Sensation. The condition of the visual system can be determined by examining various aspects of visual sensation. For example, the ability to detect and identify small objects (i.e., visual acuity) can be affected by disorders in the transparent media of the eye and/or visual nervous system. The inability to detect objects in specific areas of space (i.e., visual field defects) is often related to neural damage.

Somatisation and Somatoform Disorders The somatoform disorders are the extreme end of the scale of somatisation. So, the physical symptoms persist long-term, or are severe but no physical disease can fully explain the symptoms. Somatoform disorders include: 1  Somatisation disorder. 2  Hypochondriasis. 3  Conversion disorder. 4  Body dysmorphic disorder. 5  Pain disorder.

These taste disorders can range from obstructions in or damage to the nose to damage to the brain and nervous system in general. The most common pure taste disorder is a phantom taste sensation; this is the perception of a  bad taste in the mouth  that does not go away. The decreased ability to taste certain types of foods is known medically as hypogeusia; the absence of taste entirely is termed ageusia. Dysgeusia refers to the presence of a metallic, rancid, or foul taste in the mouth. Taking certain medications can also interfere with the ability to taste.
