Background
• MS is the most common cause of neurological disability in young adults in the UK
• Working age population
• Prevalence 80-100,000 people with MS in UK
• Leeds – population 750,000 - 858 people with MS and 45 new cases per year
![Page 4: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/4.jpg)
What is MS?
• MS is a disease of the central nervous system (CNS)
• An inflammatory reaction in the CNS causes loss of myelin and slowing of nerve conduction
• Areas of demyelination
• Loss of axons

Sites that are vulnerable to demyelination
• Optic nerves
• Brainstem
• Cervical cord
• Periventricular regions
![Page 7: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/7.jpg)
Optic neuritis
• Blurred vision or loss of vision in one eye – often central
• Pain on moving the eye
• Impaired colour vision
• Reduced visual acuity• Normal or swollen
disc• Central scotoma• Pupil relatively dilated • ‘Afferent pupillary
defect’
![Page 8: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/8.jpg)

![Page 9: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/9.jpg)
Spinal cord
• Limping or dragging one leg
• Numbness, tingling, tight band-like sensation
• L’Hermittes• Bowel and bladder
symptoms
• Increased tone, pyramidal weakness, brisk reflexes, extensor plantars
• Loss of vibration sense
• Sensory level
![Page 10: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/10.jpg)

![Page 14: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/14.jpg)
Favourable prognostic indicators

• Female sex
• Relapsing remitting course
• Optic neuritis or sensory symptoms at onset
• Few attacks during the first 5 years
![Page 15: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/15.jpg)
Making the diagnosis
• Clinical diagnosis• History: neurological
events separated in time• Examination: Signs of
damage to different areas of the CNS i.e. neurological signs separated in space
• Investigations: supportive not diagnostic
![Page 16: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/16.jpg)
Aims of treatment
• Reverse existing impairments and disability
• Prevent long-term disability
• Reduce relapse rate

April 1993
Pivotal trial of Betaseron

Disease modifying treatments
• Interferon beta 1-b• Interferon beta 1-a• Copaxone• Natalizumab• Fingolimod
![Page 19: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/19.jpg)
Interferon beta
• Reduces the number of relapses by a third
• Effective early in the disease course
• Eligibility -2 clinically significant relapses in previous 2 years
• No evidence of long-term effect on disability
![Page 20: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/20.jpg)
Outcomes for the West Yorkshire treated population
• Does treatment with a disease-modifying drug influence the quality of life of people with MS?
• Do certain groups of patient respond better than others?

• Reduces relapse rate by 60%
![Page 26: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/26.jpg)

• Uncertain/if any impact on later disease progression
• Newer drugs have different side effect profiles eg PML, cardiotoxicity
• New oral drug licensed and awaiting NICE approval

Moving On and Beyond
• New programme for people with MS, MND and Heart failure
• ‘Empowering people with life limiting conditions to take control and live a new life to the full’
![Page 29: Update on Multiple Sclerosis Helen Ford Consultant Neurologist Leeds Teaching Hospitals NHS Trust](https://reader036.vdocument.in/reader036/viewer/2022081504/56649e695503460f94b65554/html5/thumbnails/29.jpg)
Objectives• Improve access to the Hospice for non cancer
patients • Develop opportunity for peer
support/empowerment for service developers & course attendees
• Collaborative working to address survivorship and Specialist Palliative Care for non cancer patients.
• Focus on survivorship, coping & advance care planning.
