- Optic neuritis – Optic neuritis refers to inflammation that damages the optic nerve – a bundle of nerve fibres than transmit communication from the eye to the brain. It is commonly caused by MS. Optic neuritis is often one of the first signs of MS.
- Relapse-remitting MS (RRMS) – A type of MS where there are periods of remission and recovery punctuated by attacks (relapses). RRMS is a misnomer, as damage continues between attacks during periods of so-called remission, unless the disease is stabilized.
- Overcoming MS Ambassador – Overcoming MS Ambassadors serve as regional coordinators, offering advice and encouragement as people start the Overcoming MS program.
- Lumbar puncture – A procedure in which a thin needle is inserted between the bones in your lower spine, used when diagnosing MS.
- Transverse Myelitis – an inflammation of both sides of one section of the spinal cord. This neurological disorder often damages the insulating material covering nerve cell fibers (myelin).
- Disease Modifying Drugs (DMDs) – Disease-modifying therapies have been shown in clinical trials to modify the course of MS.
- Professor George Jelinek – a medical doctor who was diagnosed with MS and developed the Overcoming MS 7-Step Recovery Programme.
- MS fatigue – one of the most common MS symptoms, it is an extreme form of tiredness, one which can be debilitating and overwhelming.
- Vision problems – caused by MS can vary and can be caused by lack of coordination in the eye muscle or damage to the optic nerve.
- Tingling – Abnormal sensations of numbness, pins and needles and tingling are common in MS, and are part of a group of symptoms called paraesthesia.
- Highly Active (HA) – used to describe disease activity, not ‘type’ of MS. There is no precise agreed definition but includes frequent relapses with incomplete recovery, and/or high increase in lesions on MRI, faster loss of function after onset.
- Steroids – Steroids have been used for MS relapses for many years. Most neurologists prescribe them for acute relapses in people with relapsing-remitting MS. The evidence seems clear that they improve recovery time from individual relapses.
- Foot drop – Condition of weakness in the muscles of the leg caused by poor nerve conduction, which interferes with a person’s ability to extend the ankle and walk with a normal pattern. The toes touch the ground before the heel, causing the person to trip or lose balance.
