Paresis
In medicine, paresis (), compound word from Greek , (πᾰρᾰ- “beside” + ἵημι “let go, release”), is a condition typified by a weakness of voluntary movement, or by partial loss of voluntary movement or by impaired movement. When used without qualifiers, it usually refers to the limbs, but it can also be used to describe the muscles of the eyes ( ophthalmoparesis), the stomach (gastroparesis), and also the vocal cords ( vocal cord paresis). Neurologists use the term ''paresis'' to describe weakness, and ''plegia'' to describe paralysis in which all voluntary movement is lost. The term ''paresis'' comes from the 'letting go' from παρίημι 'to let go, to let fall'. Types Limbs * Monoparesis – One leg or one arm * Paraparesis – Both legs * Hemiparesis – The loss of function to only one side of the body * Triparesis – Three limbs. This can either mean both legs and one arm, both arms and a leg, or a combination of one arm, one leg, and face * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastroparesis
Gastroparesis (gastro- from Ancient Greek – gaster, "stomach"; and -paresis, πάρεσις – "partial paralysis") is a medical disorder of ineffective neuromuscular contractions (peristalsis) of the stomach, resulting in food and liquid remaining in the stomach for a prolonged period. Stomach contents thus exit more slowly into the duodenum of the digestive tract, a medical sign called delayed gastric emptying. The opposite of this, where stomach contents exit quickly into the duodenum, is called dumping syndrome. Symptoms include nausea, vomiting, abdominal pain, feeling full soon after beginning to eat (early satiety), abdominal bloating, and heartburn. Many or most cases are Idiopathic disease, idiopathic. The most commonly known cause is autonomic neuropathy of the vagus nerve, which innervates the stomach. Uncontrolled diabetes mellitus is a frequent cause of this nerve damage, but trauma to the vagus nerve is also possible. Some cases may be considered post-in ...

Vocal Cord Paresis
Vocal cord paresis, also known as recurrent laryngeal nerve paralysis or vocal fold paralysis, is an injury to one or both recurrent laryngeal nerves (RLNs), which control all intrinsic muscles of the larynx except for the cricothyroid muscle. The RLN is important for speaking, breathing and swallowing. The primary larynx-related functions of the mainly efferent nerve fiber RLN include the transmission of nerve signals to the muscles responsible for regulation of the vocal folds' position and tension to enable vocalization as well as the transmission of sensory nerve signals from the mucous membrane of the larynx to the brain. A unilateral injury of the nerve typically results in Dysphonia, hoarseness caused by a reduced mobility of one of the vocal folds. It may also cause minor shortages of breath as well as aspiration problems especially concerning liquids. A bilateral injury causes the vocal folds to impair the air flow resulting in breathing problems, stridor and snoring soun ...

Hemiparesis
Hemiparesis, also called unilateral paresis, is the weakness of one entire side of the body (''wikt:hemi-#Prefix, hemi-'' means "half"). Hemiplegia, in its most severe form, is the complete paralysis of one entire side of the body. Either hemiparesis or hemiplegia can result from a variety of medical causes, including congenital conditions, trauma, tumors, traumatic brain injury and stroke.Detailed article about hemiparesis at Disabled-World.com Signs and symptoms Different types of hemiparesis can impair different bodily functions. Some effects, such as weakness or partial paralysis of a limb on the affected side, are generally always to be expected. Other impairments can appear, upon external examination, to be unrelated to the limb weakness, but are nevertheless also cau ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

General Paresis
General paresis, also known as general paralysis of the insane (GPI), paralytic dementia, or syphilitic paresis is a severe neuropsychiatric disorder, classified as an organic mental disorder, and is caused by late-stage syphilis and the chronic meningoencephalitis and cerebral atrophy that are associated with this late stage of the disease when left untreated. GPI differs from mere paresis, as mere paresis can result from multiple other causes and usually does not affect cognitive function. Degenerative changes caused by GPI are associated primarily with the frontal and temporal lobar cortex. The disease affects approximately 7% of individuals infected with syphilis, and is far more common in developing countries where fewer options for timely treatment are available. It is more common among men. GPI was originally considered to be a type of madness due to a dissolute character, when first identified in the early 19th century. The condition's connection with syphilis was di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ophthalmoparesis
Ophthalmoparesis refers to weakness (-paresis) or paralysis (-plegia) of one or more extraocular muscles which are responsible for eye movements. It is a physical finding in certain neurologic, ophthalmologic, and endocrine disease. Internal ophthalmoplegia means involvement limited to the pupillary sphincter and ciliary muscle. External ophthalmoplegia refers to involvement of only the extraocular muscles. Complete ophthalmoplegia indicates involvement of both. Presentation Causes Ophthalmoparesis can result from disorders of various parts of the eye and nervous system: * Infection around the eye. Ophthalmoplegia is an important finding in orbital cellulitis. * The orbit of the eye, including mechanical restrictions of eye movement, as in Graves' disease. * The muscle, as in progressive external ophthalmoplegia or Kearns–Sayre syndrome. * The neuromuscular junction, as in myasthenia gravis. * The relevant cranial nerves (specifically the oculomotor, trochlear, and ...

Triparesis
Triparesis is a medical condition, similar to triplegia, but the major difference between the two is primarily that triplegia is total loss of function in three limbs, and triparesis denotes weakening of three limbs.

Syphilis
Syphilis () is a sexually transmitted infection caused by the bacterium ''Treponema pallidum'' subspecies ''pallidum''. The signs and symptoms depend on the stage it presents: primary, secondary, latent syphilis, latent or tertiary. The primary stage classically presents with a single chancre (a firm, painless, non-itchy Ulcer_(dermatology), skin ulceration usually between 1 cm and 2 cm in diameter), though there may be multiple sores. In secondary syphilis, a diffuse rash occurs, which frequently involves the palms of the hands and soles of the feet. There may also be sores in the mouth or vagina. Latent syphilis has no symptoms and can last years. In tertiary syphilis, there are Gumma (pathology), gummas (soft, non-cancerous growths), neurological problems, or heart symptoms. Syphilis has been known as "The Great Imitator, the great imitator", because it may cause symptoms similar to many other diseases. Syphilis is most commonly spread through human sexual activi ...

Paralysis
Paralysis (: paralyses; also known as plegia) is a loss of Motor skill, motor function in one or more Skeletal muscle, muscles. Paralysis can also be accompanied by a loss of feeling (sensory loss) in the affected area if there is sensory damage. In the United States, roughly 1 in 50 people have been diagnosed with some form of permanent or transient paralysis. The word "paralysis" derives from the Greek language, Greek παράλυσις, meaning "disabling of the nerves" from παρά (''para'') meaning "beside, by" and λύσις (''lysis'') meaning "making loose". A paralysis accompanied by involuntary tremors is usually called "palsy". Causes Paralysis is most often caused by damage in the nervous system, especially the spinal cord. Other major causes are stroke, Physical trauma, trauma with nerve injury, poliomyelitis, cerebral palsy, peripheral neuropathy, Parkinson's disease, ALS, botulism, spina bifida, multiple sclerosis and Guillain–Barré syndrome.

Monoparesis
Monoplegia is paralysis of a single limb, usually an arm. Common symptoms associated with monoplegic patients are weakness, numbness, and pain in the affected limb. Monoplegia is a type of paralysis that falls under hemiplegia. While hemiplegia is paralysis of half of the body, monoplegia is localized to a single limb or to a specific region of the body. Monoplegia of the upper limb is sometimes referred to as brachial monoplegia, and that of the lower limb is called crural monoplegia. Monoplegia in the lower extremities is not as common of an occurrence as in the upper extremities. Monoparesis is a similar, but less severe, condition because one limb is very weak, not paralyzed. For more information, see paresis. Many conditions that cause paraplegia or quadriplegia begin as monoplegia. Thus, the diagnosis of spinal paraplegia must also be consulted. In addition, multiple cerebral disorders that cause hemiplegia may begin as monoplegia. Monoplegia is also frequently associated ...
