Ataxia Main article: Cerebellar ataxia. The term cerebellar ataxia is used to indicate ataxia that is due to dysfunction of the cerebellum. The cerebellum is responsible for integrating a significant amount of neural information that is used to coordinate smoothly ongoing movements and to participate in motor planning.

2. Central Nervous System An terior cerebral artery A1 segment hypoplasia is an uncom-. mon fetal variant of the circle of Willis. The frequency of this. congenital variation is 1–13% as derived from angiograms. and autopsy reports. Impaired collateral blood flow through. the circle of Willis is a recognized risk factor for ischemic. stroke. The A1 segment of the anterior cerebral artery is a. principal supplier of anterior collateral blood flow.

Pituitary gland An explanation of the development of the pituitary gland (Hypophysis cerebri) & the congenital anomalies. In vertebrate anatomy, the pituitary gland, or hypophysis, is an endocrine gland about the size of a pea and weighing 0.5 grams (0.018 oz) in humans. It is a protrusion off the bottom of the hypothalamus at the base of the brain.

What is hypotonia? Hypotonia is a medical term used to describe decreased muscle tone. Normally, even when relaxed, muscles have a very small amount of contraction that gives them a springy feel and provides some resistance to passive movement.

Hypophosphatasia Perinatal hypophosphatasia is the most pernicious form of hypophosphatasia. In utero, profound hypomineralization results in caput membranaceum, deformed or shortened limbs during gestation and at birth and rapid death due to respiratory failure. Stillbirth is not uncommon and long-term survival is rare.

Description Bilateral vestibular hypofunction (BVH) is a heterogeneous condition that results from defects in either the vestibular organs, eighth cranial nerves, or a combination of the two.[1][2][3] This condition causes impairments in the vestibulo-ocular reflex (VOR) and the major functions of the vestibular organs.

Achondroplasia Achondroplasia is a form of short-limbed dwarfism. Cartilage is a tough but flexible tissue that makes up much of the skeleton during early development. However, in achondroplasia the problem is not in forming cartilage but in converting it to bone (a process called ossification), particularly in the long bones of the arms and legs.

Hypoplasia Hypoplasia (from ancient Greek ὑπo-hypo- , under + πλάσις plasis, formation; adjective form hypoplastic) is underdevelopment or incomplete development of a tissue or organ. Although the term is not always used precisely, it properly refers to an inadequate or below-normal number of cells. Hypoplasia is similar to aplasia, but less severe. It is technically not the opposite of hyperplasia (too many cells). Hypoplasia is a congenital condition, while hyperplasia generally refers to excessive cell growth later in life. (Atrophy, the wasting away of already existing cells, is technically the direct opposite of both hyperplasia and hypertrophy.). Hypoplasia can be present in any tissue or organ.

- Cerebellar ataxia can encompass a variety of different problems with coordination and balance. These will include a staggering gait often with a prominent goose stepping of the front limbs, crossing over of the limbs, and balance problems.

Feline Cerebellar Hypoplasia Almost all dogs and cats with congenital cerebellar hypoplasia can live happily as pets with a little special care to compensate for their disabilities. This condition can be confused with cerebellar abiotrophy, a different disorder in dogs in which the puppy has a normal cerebellum at birth but it gradually dies.

- It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux. However, due to seasonal lag, June, July, and August are the hottest months in the northern hemisphere and December, January, and February are the hottest months in the southern hemisphere.

Top 20 Doctor insights on: Cerebellar Atrophy Prognosis 2 doctors agreed: Shrinkage: The cerebellum is a posterior area of the brain important in balance and coordination. Atrophy implies this area is shrinking in size. Some causes could include alcohol abuse, hereditary spinocerebellar degenerations, and chronic ms.

Hypophosphatasia Hypophosphatasia (HPP) is an inborn error of metabolism with highly variable clinical severity caused by loss-of-function mutations in the gene encoding tissue nonspecific alkaline phosphatase (TNSALP). The prevalence of the severe form is estimated to be between 1/100,000 and 1/300,000.

- Acta Neurologica Taiwanica Vol 21 No 1 March 2012. Abstract. Congenital vertebral artery (VA) hypoplasia is an uncommon embryonic variation of posterior circulation. The frequency of this congenital variation was reported to be 2-6% from autopsy and angiograms. Is it a congenital risk factor of ischemic stroke? In this review, we gave an overview of the literature concerning vertebral artery hypoplasia. VA hypoplasia served as an independent factor of a reduction of the posterior. circulation blood flow velocity. VA hypoplasia can play a negative role in cases of occlusion of a major. brain vessel since it limits the potential of compensatory blood circulation.
