Specific Conditions/ Disabilities

Agenesis of the corpus callosum

Is a rare birth defect (congenital disorder) in which there is a complete or partial absence of the corpus callosum. It occurs when the corpus callosum, the band of white matter connecting the two hemispheres in the brain, fails to develop normally, typically during pregnancy. Some characteristics common in individuals with callosal disorders  include vision impairments, low muscle tone (hypotonia), poor motor coordination, delays in  motor milestones such as sitting and walking, low perception of pain, delayed toilet training, and chewing and swallowing difficulties. Laboratory research has demonstrated that individuals with ACC have difficulty transferring more complex information from one hemisphere to the other.  They also have been shown to have some cognitive disabilities (difficulty in complex problem solving) and social difficulties (missing subtle social cues), even when their intelligence quotient is normal.

Anaemia

From Greek meaning lack of blood, is a decrease in number of red blood cells or less than the normal quantity of hemoglobin in the blood.
Most commonly, people with anemia report feelings of weakness, or fatigue, general malaise, and sometimes poor concentration. They may also report dyspnea (shortness of breath) on exertion.

Anorexia

Anorexia nervosa is a serious mental health condition. It’s an eating disorder where a person keeps their body weight as low as possible. People with anorexia usually do this by restricting the amount of food they eat, making themselves vomit, and exercising excessively.

Anterior horn cell disorder

Anterior horn cell disease is a neurological disorder that affects the nerve cells of the spinal cord. The disorder affects the voluntary skeletal muscles of the muscular system

Aphasia

Aphasia is a condition that affects the brain and leads to problems using language correctly. People with aphasia make mistakes with the words they use, sometimes using the wrong sounds in a word, choosing the wrong word, or putting words together incorrectly.

Ataxia

Ataxia is a term for a group of disorders that affect co-ordination, balance and speech. Any part of the body can be affected, but people with ataxia often have difficulties with balance and walking, speaking, swallowing, tasks that require a high degree of control, such as writing and eating and vision

Bartter Syndrome

Is a group of similar kidney disorders that cause an imbalance of potassium, sodium, chloride, and other molecules in the body. It is caused by a mutation in any one of 5 genes. In some cases, the condition manifests before birth, affected infants typically do not grow and gain weight as expected. Dehydration, constipation and increase urine production are the result of losing too much salt in the urine. Weakening of the bones can occur due to excess loss of calcium, and muscle weakness, cramping and fatigue occur due to low levels of potassium in the blood. The different types of Bartter Syndrome are classified according to the age of onset, severity, and the specific gene that causes the condition.

Is a rare genetic muscular disorder present at birth characterised by a facial weakness or paralysis, and a small or retracted chin and clef palate.

Cerebral palsy

Is caused by damage to the motor control centres of the developing brain and can occur during pregnancy, during childbirth or after birth up to about age three.  Resulting limits in movement and posture cause activity limitation and are often accompanied by disturbances of sensation, depth perception, and other sight-based perceptual problems, communication ability; impairments can also be found in cognition, and epilepsy is found in about one-third of cases.

CHARGE

The name CHARGE is an abbreviation for several of the features common in the disorder: coloboma (an eye condition), heart defects, atresia choanae (a problem behind the nose), growth retardation, genital abnormalities, and ear abnormalities.

Chiari malformation

Previously called an Arnold-Chiari malformation, is where the lower part of the brain pushes down into the spinal canal. This defect usually develops before birth. Some people with Chiari malformations may have no symptoms. Others may have symptoms such as: dizziness , muscle weakness, numbness, vision problems, headaches and problems with balance and coordination. Chiari malformations affect females more often than males.

Chronic fatigue syndrome

Is the common name for a group of significantly debilitating medical conditions characterized by  persistent fatigue and other specific symptoms that lasts for a minimum of six months in adults (and 3 months in children or adolescents). The fatigue is not due to exertion, not significantly relieved by rest, and is not caused by other medical conditions .
Symptoms of CFS include malaise after exertion; unrefreshing sleep, widespread muscle and joint pain, sore throat, headaches of a type not previously experienced, cognitive difficulties, chronic and severe mental and physical exhaustion, and other characteristic symptoms in a previously healthy and active person.  Additional symptoms may be reported, including muscle weakness, increased sensitivity to light, sounds and smell, orthostatic intolerance, digestive disturbances,  depression, painful and often slightly swollen lymph nodes, cardiac and respiratory problems

Is a type of inflammatory bowel disease that may affect any part of the gastrointestinal tract , causing a wide variety of symptoms. It primarily causes abdominal pain, diarrhoea,  vomiting or weight loss, but may also cause complications outside the gastrointestinal tract such as skin rashes, arthritis, inflammation of the eye, tiredness, and lack of concentration.

Chronic Fatigue

Syndrome (CFS) is a debilitating disorder characterized by extreme fatigue or tiredness that doesn’t go away with rest and can’t be explained by an underlying medical condition.

Is an autosomal recessive genetic disorder that affects most critically the lungs, and  also the pancreas, liver, and intestine.  Difficulty breathing is the most serious symptom.  Other symptoms, include sinus infections, poor growth, and infertility.

Dandy Walker Syndrome

Is a form of Hydrocephalus. Dandy–Walker syndrome is a rare group of congenital human brain malformations. There are three subtypes which affect multiple organs to varying degrees, but the fundamental abnormalities involve the cerebellum[1] which controls muscle coordination.

Dissociative identity disorder (DID)

Dissociative identity disorder (DID), previously known as multiple personality disorder, is a mental disorder characterized by at least two distinct and relatively enduring personality states. This is accompanied by memory gaps beyond what would be explained by ordinary forgetfulness. These states alternately show in a person’s behavior; presentations, however, are variable.

 Down syndrome

Is the most common chromosome abnormality in humans.  It is typically associated with a delay in cognitive ability and physical growth, and a particular set of facial characteristics. Language skills show a difference between understanding speech and expressing speech, and commonly individuals with Down syndrome have a speech delay.  Fine motor skills are delayed and often lag behind gross motor skills and can interfere with cognitive development. Effects of the condition on the development of gross motor skills are quite variable.  A large proportion of individuals with Down syndrome have a severe degree of intellectual disability.

Duchenne muscular dystrophy

Is a recessive X-linked form of muscular dystrophy, affecting around 1 in 3,600 boys, which results in muscle degeneration and eventual death.
Later symptoms may include abnormal bone development that lead to skeletal deformities, including curvature of the spine. Due to progressive deterioration of muscle, loss of movement occurs, eventually leading to paralysis. Intellectual impairment may or may not be present but if present, does not progressively worsen as the child ages.

Dyscalculia

Is a specific learning disability involving innate difficulty in learning or comprehending arithmetic. It is akin to dyslexia and includes difficulty in understanding numbers, learning how to manipulate numbers, learning maths facts, and a number of other relate symptoms.

Dysexecutive Syndrome

Dysexecutive Syndrome is a neurological impairment of executive function, where people have trouble with complex thinking and reasoning tasks. It is most commonly seen in people with brain injuries. Some mental health conditions and cognitive disabilities can also create signs of dysexecutive syndrome

Dysphasia     

Is a partial or complete impairment of the ability to communicate resulting from brain injury.
Dysphasia can occur in a variety of forms, depending on how the communicative disruption manifests.
Classically, dysphasia can affect one or more of the basic language functions: comprehension (understanding spoken language), naming (identifying items with words), repetition (repeating words or phrases), and speech.
Dysphasia does not necessarily prevent proper cognitive function, so the person can think and feel with perfect clarity. This can be extremely frustrating for the patient, as they cannot express these thoughts and feelings to others.

Dysgraphia

Is a neurological disorder, characterised by a difficulty with handwriting.

Dystonia

Dystonia is a medical term for a range of movement disorders that cause muscle spasms and contractions. The spasms and contractions may either be sustained or may come and go. Movements are often repetitive and cause unusual, awkward and sometimes painful postures.

The condition cannot be cured, however therapy can help manage symptoms, and improve quality of life.

Mitochondrial Disorder

The mitochondria in the cells are not producing enough energy. Sometimes they are not very efficient or they don’t not work at all. There is a huge variety in the symptoms and the severity of Mitochondrial Disease. It depends on how many cells are affected and where they are in the body. Everyone is affected differently.
