Neuroscience  Facts

Ø  Social Ties Preserve Memory, Slow Brain Aging
A strong social network could be the key to preserving memory. New research has found that mice housed in groups had better memories and healthier brains than animals that lived in pairs.

Ø  For Anxiety, a Single Intervention Is Not Enough
No matter which treatment they get, only 20 percent of young people diagnosed with anxiety will stay well, researchers report.

Ø  Memory Depends On Protein 'Off-Switch'
Memory, learning and cognitive flexibility depend on a protein 'off-switch' in the brain, according to a breakthrough discovery.

Ø  Hormone Therapy: Better Cognitive Function?
A new study shows how, in the right dosage and combination, hormones also may slow cognitive decline in postmenopausal women as they age.

Workshop  on Different optic Neuropathies and Novel Treatments

Umur Kayabasi, 

Bahcesehir University, Turkey


The aim of this workshop is to discuss the diagnosis, treatment and follow- up of different optic neuropathies. Meanwhile images from the new technology devices like OCT and the conventional machines like Perimetry will be shown. Also MR images of the orbit and brain and images of optic nerve problems will be the subjects of the main topic. There are some new developments in the treatment of the optic neuropathies and different ideas about novel treatments will be shared.

OPTİC NEUROPATHİES:  Optic neuritis ( demyelination of the optic nerve): Acute, painful vision loss. Occurs mainly in women within the age range of 18- 45. Responds well to high dose intravenous steroids. Approximately 1/3 of the cases are seen with disc edema, 2/3 are retrobulber. Retrobulber cases progress to multiple sclerosis (MS ) more frequently. The possibility of a woman patient to develop MS after isolated optic neuritis is about % 70 in ten years. The progression of optic neuritis to MS can be detected by OCT.

Anterior ischemic optic neuropathy (non- arteritic): Acute, painless visual loss due to a stroke on the optic nerve head. Disc edema is present. Patients usually have hypertension or diabetes. Visual field defect is altitudinal. Cup to disc ratio is small. No definite treatment. Intravitreal injections (triamcinolone and anti- VEGF) may be tried in acute cases. 

Traumatic optic neuropathy: Occurs after a direct or indirect trauma to the optic nerve. Steroids are not recommended if there is head concussion. Surgery of the optic canal to decompress the nerve may be tried in early stages. There are reports about success with intravenous erythropoietin.
Toxic optic neuropathy: Central, bilateral visual loss. There is a new report about improvement after methanol toxicity with the combination of erythropoietin and steroids.

Radiation optic neuropathy: Bilateral visual loss months or years after radiation therapy of a brain tumor. There are new reports of improvement of vision with intravenous bevacizumab tharapy.

Leber’ s optic neuropathy: Painless,bilateral visual loss with central scotomas. Inherited by the maternal mitochondrial DNA mutations: m.11778, m.14484, m.3460. Idebenone treatment in early stage Leber?s disease have been shown to be beneficial. 

Chronic relapsing inflammatory optic neuropathy: Steroid sensitive optic neuropathy which recurs after steroid withdrawal. Long term steroids or other immunosuppressive agents are used. There are other optic neuropathies with inflammatory, infectious, etc. etiology which can be discussed, too.

What Causes Prion Disease?

Prion diseases are associated with the build up in the brain (and some other organs) of an abnormal or ‘rogue’ form of a naturally occurring cellular protein, known as the prion protein. The rogue protein results from a change in shape of the normal prion protein.  Once formed in the body these rogue proteins recruit and convert more of the normal prion protein into the abnormal form, setting off a kind of chain reaction which leads to a progressive accumulation of the rogue protein.  In the normal course of events, once they have served their purpose, prion proteins are broken down by enzymes in the body.  The abnormal prions however are more resistant to this process; so they accumulate and cause damage in the brain, which interferes with normal brain functioning.  All forms of the disease are thought to be associated with an incubation period.  This is a clinically 'silent phase' during which replication of the rogue protein is thought to be taking place.


Genetic Susceptibility

At a particular position in the prion gene known as codon 129, there are two possible genetic types, which in turn specify the body to produce different amino acids at this position.  These amino acids are called methionine and valine, or M and V for short.  In most countries, MM and MV frequencies in the population are roughly equal (40-50%).  It has been known for some years that individuals, who are MV, are at much less risk of developing prion disease than are MM or VV individuals .

Demyelinating Diseases

Most of the nerves in your body are covered with a protective layer called myelin. It’s a lot like the insulation on electric wires. It helps messages from your brain move quickly and smoothly through your body, the way electricity flows from a power source.

Demyelinating disorders are any conditions that damage myelin. When this happens, scar tissue forms in its place. Brain signals can’t move across scar tissue as quickly, so your nerves don’t work as well as they should.

Multiple sclerosis

Multiple sclerosis (MS) is the most common demyelinating disease of the central nervous system. In this disorder, your immune system attacks the myelin sheath or the cells that produce and maintain it. This causes inflammation and injury to the sheath and ultimately to the nerve fibers that it surrounds. The process can result in multiple areas of scarring (sclerosis).

Other causes

·         Other types of demyelinating disease and their causes include:
·         Optic neuritis — inflammation of the optic nerve in one or both eyes
·         Neuromyelitis optica (Devic's disease) — inflammation and demyelination of the central nervous system, especially of the optic nerve and spinal cord
·         Transverse myelitis — inflammation of the spinal cord
·         Acute disseminated encephalomyelitis — inflammation of the brain and spinal cord
·         Adrenoleukodystrophy and adrenomyeloneuropathy — rare, inherited metabolic disorders
·         MS and other demyelinating diseases most commonly result in vision loss, muscle weakness, muscle stiffness and spasms, loss of coordination, change in sensation, pain, and changes in bladder and bowel function.


·         No cures exist for demyelinating diseases and their progression, and symptoms are different for everyone. Getting treatment early is important. Treatment focuses on:
·         Minimizing the effects of the attacks
·         Modifying the course of the disease
·         Managing the symptoms
·         A variety of drug therapies are recommended depending on your specific disorder. Strategies to treat symptoms include physical therapy, muscle relaxing drugs, and medications to reduce pain and fatigue. Talk with your doctor about the best course of treatment for your specific disorder.
