Does the extent of axonal loss and demyelination from chronic lesions in multiple sclerosis correlate with the clinical subgroup? (1/51)
OBJECTIVE: To determine non-invasively the relation between the degree of axonal loss and the extent of demyelination in chronic lesions visible on MRI in patients with different subgroups of clinically definite multiple sclerosis using (1)H magnetic resonance spectroscopy ((1)H MRS) and magnetisation transfer imaging (MT). Conventional MRI is unable to differentiate between the various pathological processes occurring in the multiple sclerosis lesion. There are, however, newer MR techniques which show promise in this respect. METHODS: (1)H MRS and MT were performed in 18 patients with clinically definite multiple sclerosis who had a wide range of disability and disease duration. RESULTS: A significant correlation was found between a reduction in the concentration of N-acetyl aspartate (NAA; an in vivo marker of axonal loss or dysfunction) and a reduction in MT ratio (a probable marker of demyelination) in patients who had entered the secondary progressive stage of the disease. Patients with minimal disability after a disease duration of greater than 10 years-so called benign multiple sclerosis-showed a relative preservation of NAA and MT. CONCLUSIONS: Because a reduction in MT seems to be a relative marker for demyelination and a reduction of NAA from chronic lesions is indicative of axonal loss, this study supports the hypothesis that demyelination and axonal loss occur in the same chronic multiple sclerosis lesions. In addition, the degree of axonal loss and demyelination correlates with clinical heterogeneity. (+info)Slowly progressive dystonia following central pontine and extrapontine myelinolysis. (2/51)
A 28-year-old woman was hospitalized with dysarthria and oro-mandibular and upper limb dystonia. Approximately 8 years prior to the current admission, the woman became severely hyponatremic due to traumatic subarachnoid hemorrhage-related SIADH. Brain MRIs showed a signal increase in the central pons, thalamus and striatum on T2 weighted images compatible with central pontine and extrapontine myelinolysis. From a few months after that event, dystonia progressed slowly over the subsequent 8 years. We speculate that the particular damage chiefly to the myelin structures by myelinolytic process may have caused an extremely slow plastic reorganization of the neural structures, giving rise to progressive dystonia.

Hyponatremia is a frequent electrolyte disorder. A hyponatremia is called acute severe (<115 mM) when the duration has been <36 to 48 h. Such patients often have advanced symptoms as a result of brain edema. Acute severe hyponatremia is a medical emergency. It should be corrected rapidly to approximately 130 mM to prevent permanent brain damage. In contrast, in chronic severe hyponatremia (>4 to 6 d), there is no brain edema and symptoms are usually mild. In such patients, a number of authors have recommended a correction rate <0.5 mM/h to approximately 130 mM to minimize the risk of cerebral myelinolysis. Sometimes it is not possible to diagnose whether a severe hyponatremia is acute or chronic. In such cases, an initial imaging procedure is helpful in deciding whether rapid or slow correction should be prescribed. The modalities of treatment of severe hyponatremia have so far consisted of infusions of hypertonic saline plus fluid restriction. In the near future, vasopressin antagonists will become available. Preliminary experience has already demonstrated their efficiency of inducing a sustained water diuresis and a correction of hyponatremia. (+info)MR imaging of seven presumed cases of central pontine and extrapontine myelinolysis. (4/51)
MRI was performed in seven patients with presumed central pontine and extrapontine myelinolysis. The underlying diseases were diabetes, lung cancer, Wilson disease, trauma, alcoholism, renal insufficiency and hemodialysis. CPM was found in four cases (in two of them extrapontine lesions were considered as resulting from Wilson disease), CPM and EPM in three patients. The localization of extrapontine changes included cerebellum, cerebral peduncles, caudate and lentiform nuclei, internal capsules, white matter and cortex of the cerebrum. (+info)Decreased diffusion in central pontine myelinolysis. (5/51)
Two patients with central pontine myelinolysis (CPM) were studied with diffusion-weighted MR imaging 1 week after onset of tetraplegia. In both patients, affected white matter showed hyperintensity on diffusion-weighted images associated with a decrease in apparent diffusion coefficient (ADC) values. In one patient studied serially, ADC values normalized by 3 weeks after tetraplegia. Early in the clinical course, diagnosis of CPM can sometimes be difficult. Hyperintensity on diffusion-weighted images may therefore have diagnostic utility. Decreased lesional ADC values support the notion that CPM is a consequence of relative intracellular hypotonicity.

Central Pontine Myelinolysis (CPM) is a rare neurologic complication after liver transplantation. The true incidence of CPM after orthotopic liver transplantation remains an estimate. However, with the introduction of magnetic resonance imaging, early recognition became feasible. In this report, we present a case of rapid resolution of CPM followed by serial magnetic resonance imaging scans. (+info)A 47-year-old alcoholic man with progressive abnormal gait. (7/51)
Central pontine myelinolysis should be considered in the differential diagnosis of a patient with a history of alcoholism and malnutrition presenting with ataxia, regardless of serum sodium values. T2-weighted images are the most sensitive imaging technique, but changes may not be evident for weeks after the insult, and in addition, the insult may not be known. Supportive care is important to prevent complications, but no treatment has been found to be effective in treating the illness. Patient outcomes vary considerably and are difficult to predict. (+info)Central pontine myelinolysis associated with hypokalaemia in anorexia nervosa. (8/51)
A 31-year-old man was admitted to hospital with of anorexia, binge eating, and self induced vomiting. On admission, he showed a pronounced low weight and disturbance of the body image and was diagnosed as having anorexia nervosa. In addition, electrolyte abnormalities, mainly hypokalaemia, and increased serum renin and aldosterone concentrations were recorded, suggesting pseudo-Bartter syndrome as a complication. Under frequent monitoring of the serum potassium and sodium concentrations, serum electrolytes were gradually corrected, but brain magnetic resonance imaging revealed reversible central pontine myelinolysis (CPM). Although attention has been mainly paid to the association of CPM with rapid correction of hyponatraemia and abnormal osmolality, this case report strongly suggested the involvement of hypokalaemia in the pathogenesis of CPM. (+info)Central pontine myelinolysis (CPM) is a neurological disorder that results from the damage to the myelin sheath in the central pons region of the brainstem. Myelin is the fatty substance that insulates and protects nerve fibers, allowing for the efficient transmission of electrical signals.
In CPM, the myelin sheath in the center of the pons area becomes damaged or destroyed due to various factors, most commonly rapid correction of hyponatremia (low sodium levels in the blood). This rapid correction can lead to an osmotic shift of water from inside the cells to outside, causing swelling and damage to the myelin sheath.
CPM is characterized by the development of symmetrical lesions in the central pons region, which can result in a range of neurological symptoms, including weakness or paralysis of muscles, difficulty swallowing, speech impairment, and altered levels of consciousness. In severe cases, CPM can lead to coma, respiratory failure, and even death.
It's important to note that the management of CPM involves preventing further damage to the myelin sheath by avoiding rapid correction of hyponatremia and providing supportive care for the neurological symptoms. Currently, there is no specific treatment for CPM, and recovery can be slow and incomplete.
Hyponatremia is a condition characterized by abnormally low sodium levels in the blood, specifically levels less than 135 mEq/L. Sodium is an essential electrolyte that helps regulate water balance in and around your cells and plays a crucial role in nerve and muscle function. Hyponatremia can occur due to various reasons, including certain medical conditions, medications, or excessive water intake leading to dilution of sodium in the body. Symptoms may range from mild, such as nausea, confusion, and headache, to severe, like seizures, coma, or even death in extreme cases. It's essential to seek medical attention if you suspect hyponatremia, as prompt diagnosis and treatment are vital for a favorable outcome.
The pons is a part of the brainstem that lies between the medulla oblongata and the midbrain. Its name comes from the Latin word "ponte" which means "bridge," as it serves to connect these two regions of the brainstem. The pons contains several important structures, including nerve fibers that carry signals between the cerebellum (the part of the brain responsible for coordinating muscle movements) and the rest of the nervous system. It also contains nuclei (clusters of neurons) that help regulate various functions such as respiration, sleep, and facial movements.
Hypernatremia is a medical condition characterized by an abnormally high concentration of sodium (na+) in the blood, specifically a serum sodium level greater than 145 mEq/L. Sodium is an essential electrolyte that helps regulate water balance in and around your cells. It's crucial for many body functions, including the maintenance of blood pressure, regulation of nerve and muscle function, and regulation of fluid balance.
Hypernatremia typically results from a deficit of total body water relative to solute, which can be caused by decreased water intake, increased water loss, or a combination of both. Common causes include dehydration due to severe vomiting or diarrhea, excessive sweating, burns, kidney diseases, and the use of certain medications such as diuretics.
Symptoms of hypernatremia can range from mild to severe and may include thirst, muscle weakness, lethargy, irritability, confusion, seizures, and in extreme cases, coma or even death. Treatment typically involves correcting the underlying cause and gradually rehydrating the individual with intravenous fluids to restore normal sodium levels.
Medical Definition of Water Intoxication:
Water intoxication, also known as hyponatremia, is a condition that occurs when an individual consumes water in such large quantities that the body's electrolyte balance is disrupted. This results in an abnormally low sodium level in the blood (hyponatremia), which can cause symptoms ranging from mild to severe, including nausea, headache, confusion, seizures, coma, and even death in extreme cases. It's important to note that water intoxication is rare and typically only occurs in situations where large amounts of water are consumed in a short period of time, such as during endurance sports or when someone is trying to intentionally harm themselves.
Demyelinating diseases are a group of disorders that are characterized by damage to the myelin sheath, which is the protective covering surrounding nerve fibers in the brain, optic nerves, and spinal cord. Myelin is essential for the rapid transmission of nerve impulses, and its damage results in disrupted communication between the brain and other parts of the body.
The most common demyelinating disease is multiple sclerosis (MS), where the immune system mistakenly attacks the myelin sheath. Other demyelinating diseases include:
1. Acute Disseminated Encephalomyelitis (ADEM): An autoimmune disorder that typically follows a viral infection or vaccination, causing widespread inflammation and demyelination in the brain and spinal cord.
2. Neuromyelitis Optica (NMO) or Devic's Disease: A rare autoimmune disorder that primarily affects the optic nerves and spinal cord, leading to severe vision loss and motor disability.
3. Transverse Myelitis: Inflammation of the spinal cord causing damage to both sides of one level (segment) of the spinal cord, resulting in various neurological symptoms such as muscle weakness, numbness, or pain, depending on which part of the spinal cord is affected.
4. Guillain-Barré Syndrome: An autoimmune disorder that causes rapid-onset muscle weakness, often beginning in the legs and spreading to the upper body, including the face and breathing muscles. It occurs when the immune system attacks the peripheral nerves' myelin sheath.
5. Central Pontine Myelinolysis (CPM): A rare neurological disorder caused by rapid shifts in sodium levels in the blood, leading to damage to the myelin sheath in a specific area of the brainstem called the pons.
These diseases can result in various symptoms, such as muscle weakness, numbness, vision loss, difficulty with balance and coordination, and cognitive impairment, depending on the location and extent of the demyelination. Treatment typically focuses on managing symptoms, modifying the immune system's response, and promoting nerve regeneration and remyelination when possible.
Dystonia is a neurological movement disorder characterized by involuntary muscle contractions, leading to repetitive or twisting movements. These movements can be painful and may affect one part of the body (focal dystonia) or multiple parts (generalized dystonia). The exact cause of dystonia varies, with some cases being inherited and others resulting from damage to the brain. Treatment options include medications, botulinum toxin injections, and deep brain stimulation surgery.
Medical Definition:
Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic imaging technique that uses a strong magnetic field and radio waves to create detailed cross-sectional or three-dimensional images of the internal structures of the body. The patient lies within a large, cylindrical magnet, and the scanner detects changes in the direction of the magnetic field caused by protons in the body. These changes are then converted into detailed images that help medical professionals to diagnose and monitor various medical conditions, such as tumors, injuries, or diseases affecting the brain, spinal cord, heart, blood vessels, joints, and other internal organs. MRI does not use radiation like computed tomography (CT) scans.
Brain diseases, also known as neurological disorders, refer to a wide range of conditions that affect the brain and nervous system. These diseases can be caused by various factors such as genetics, infections, injuries, degeneration, or structural abnormalities. They can affect different parts of the brain, leading to a variety of symptoms and complications.
Some examples of brain diseases include:
1. Alzheimer's disease - a progressive degenerative disorder that affects memory and cognitive function.
2. Parkinson's disease - a movement disorder characterized by tremors, stiffness, and difficulty with coordination and balance.
3. Multiple sclerosis - a chronic autoimmune disease that affects the nervous system and can cause a range of symptoms such as vision loss, muscle weakness, and cognitive impairment.
4. Epilepsy - a neurological disorder characterized by recurrent seizures.
5. Brain tumors - abnormal growths in the brain that can be benign or malignant.
6. Stroke - a sudden interruption of blood flow to the brain, which can cause paralysis, speech difficulties, and other neurological symptoms.
7. Meningitis - an infection of the membranes surrounding the brain and spinal cord.
8. Encephalitis - an inflammation of the brain that can be caused by viruses, bacteria, or autoimmune disorders.
9. Huntington's disease - a genetic disorder that affects muscle coordination, cognitive function, and mental health.
10. Migraine - a neurological condition characterized by severe headaches, often accompanied by nausea, vomiting, and sensitivity to light and sound.
Brain diseases can range from mild to severe and may be treatable or incurable. They can affect people of all ages and backgrounds, and early diagnosis and treatment are essential for improving outcomes and quality of life.
Sodium is an essential mineral and electrolyte that is necessary for human health. In a medical context, sodium is often discussed in terms of its concentration in the blood, as measured by serum sodium levels. The normal range for serum sodium is typically between 135 and 145 milliequivalents per liter (mEq/L).
Sodium plays a number of important roles in the body, including:
* Regulating fluid balance: Sodium helps to regulate the amount of water in and around your cells, which is important for maintaining normal blood pressure and preventing dehydration.
* Facilitating nerve impulse transmission: Sodium is involved in the generation and transmission of electrical signals in the nervous system, which is necessary for proper muscle function and coordination.
* Assisting with muscle contraction: Sodium helps to regulate muscle contractions by interacting with other minerals such as calcium and potassium.
Low sodium levels (hyponatremia) can cause symptoms such as confusion, seizures, and coma, while high sodium levels (hypernatremia) can lead to symptoms such as weakness, muscle cramps, and seizures. Both conditions require medical treatment to correct.
Liver transplantation is a surgical procedure in which a diseased or failing liver is replaced with a healthy one from a deceased donor or, less commonly, a portion of a liver from a living donor. The goal of the procedure is to restore normal liver function and improve the patient's overall health and quality of life.
Liver transplantation may be recommended for individuals with end-stage liver disease, acute liver failure, certain genetic liver disorders, or liver cancers that cannot be treated effectively with other therapies. The procedure involves complex surgery to remove the diseased liver and implant the new one, followed by a period of recovery and close medical monitoring to ensure proper function and minimize the risk of complications.
The success of liver transplantation has improved significantly in recent years due to advances in surgical techniques, immunosuppressive medications, and post-transplant care. However, it remains a major operation with significant risks and challenges, including the need for lifelong immunosuppression to prevent rejection of the new liver, as well as potential complications such as infection, bleeding, and organ failure.
A fatal outcome is a term used in medical context to describe a situation where a disease, injury, or illness results in the death of an individual. It is the most severe and unfortunate possible outcome of any medical condition, and is often used as a measure of the severity and prognosis of various diseases and injuries. In clinical trials and research, fatal outcome may be used as an endpoint to evaluate the effectiveness and safety of different treatments or interventions.
