Progressive degeneration of motor neurones in
the following areas:
Anterior horn cells - resulting in Lower Motor
Neurone Lesions (LMN)
Cortico spinal tract cells - resulting in Upper Motor
Neurone Lesions (UMN)
Cortico bulbar tracts – resulting in UMN lesions in
areas controlling the oropharyngeal muscles
Motor Nuclei in brain stem - resulting in both
Upper and Lower Motor Lesions.
Four Main Patterns. Commonest is
1. Amyotrophic Lateral Sclerosis (65%)
•
Begins in a limb, trunk or respiratory muscles.
•
Both upper and lower motor neurones (UMN & LMN) may be
involved
•
Characterised by: muscle weakness, spasticity,
hyperreflexia , emotional lability, fasciculations, weight loss.
•
Usually progresses (80% of cases) to include progressive
bulbar palsy symptoms.
•
Average survival 2-5 years from onset of first symptoms.
2. Progressive Bulbar Palsy (PBP) A form of ALS Affects ~ 22% of
all MND diagnoses.
UMN & LMN may be involved. Typified by dysarthria and
dysphagia.
LMN damage: nasal speech, regurgitation of fluids via nose,
tongue atrophy and fasciculation, pharyngeal weakness.
UMN damage: tongue spasticity, explosive dysarthria, emotional
lability.
Slightly more women than men affected.
Average survival 6 months to 3 years from onset of symptoms
3. Progressive Muscular Atrophy (PMA) Affects
about 10% of all MND diagnoses.
Defined as a disease of purely LMN degeneration,
however a significant number of cases develop subclinical and, eventually, overt UMN signs.
Characterised by: muscle weakness, wasting,
weight loss and fasciculation. Affects men 5 times
more commonly than women.
Younger age of onset: average survival five years
plus.
4. Primary Lateral Sclerosis (PLS)
Approximately 2% of all MND diagnoses.
Only upper motor neurones damaged. Characterised
by muscle weakness, stiffness of limbs and
increased reflex response. Men are affected twice as
often as women.
Onset usually after 50 years of age:
Survival similar to normal life span.
Considerable overlap between 4 clinical syndromes
outlined as disease progresses towards more
generalised weakness.
Onset is insidious.
Early symptoms may include: stumbling, foot drop,
weakened grip, slurred speech, cramp, muscle
wasting and/or tiredness.
Rarely, presents with acute respiratory weakness.
1.Riluzole (Rilutek) is the only drug available to treat
MND. It was licensed in 1996 and NICE approval
was obtained for the treatment of MND in 2001.
Riluzole acts by modulating the pre-synaptic release
of glutamate.
2.A baseline respiratory assessment and discussion
of future support options should be undertaken as
soon as possible after diagnosis, by specialist team.

Carer networks
1.Register patient on supportive/palliative care register, with key
contact person.
2.Provide relationship based continuity as far as possible to
patient and/or carer. (Monitoring and assessment)
3.Information gathering (give current and anticipatory
information; liase with specialist teams)
4. Coordinate and refer as needed
5. Symptom management plans: coordinate, develop, share.
1.Patient identified as having MND/flagged on IT system
2.Carers identified and flagged.
3.Key contact people in primary and secondary care teams easily
identifiable on IT system
4.OOH informed of diagnosis and key issues with frequent update
5.ACP/ ADRT decisions clearly communicated
6.DNACPR status identified and communicated to ambulance and
OOH
7.End of life care preferences communicated as and when
appropriate.
1.Environment: Will home be suitable? Adaptations? (OT)
2.Changes in ability to speak/communicate/swallow? (SALT)
3.Respiratory Compromise: Ventilatory support? Home oxygen?
4.Loss of function (physiotherapy)
5.Emotional implications (psychology, support resources)
6.Care and respite needs? (Social work)
7. End of life (advance care planning, ADRT, DNACPR)
80% affected
Causes:
• Weakness & wasting of: Tongue lips facial
muscles pharynx and larynx
• Reduced palatal elevation, which can lead to
“hyper-nasal voice quality.”
• Reduced breath support, which can lead to
reduced volume or “breathy” voice quality.
Impact:
Progressive difficulty with articulation, slurred
speech and/or loss of volume. May lead to anarthria
Role of SALT:
Examine the patient’s range of movement in their lips, tongue and palate
or will carry out an oromotor examination; Advise on communication
strategies; Arrange for reassessment and provision of communication
aids such as Lightwriters and other aids.
Role of OT :
Seating, positioning, wrist and head supports; Switches and pointers;
Mobile arm supports, tables to access communication aids;
Environmental controls.
Role of Everyone:
Take time and create a quiet relaxed atmosphere; Ascertain individual’s
own preferred communication strategy and/or equipment used; Position face to face, watch lips, eyes, gestures.
Always be aware of the impact of emotion and fatigue on ability to
communicate
Cause: Weakness and paralysis of the oropharyngeal
muscles resulting from affected gIossopharyngeal, vagus,
accessory and hypoglossal nerves.
Effect: The first sign of early dysphagia may be problems
when swallowing liquids resulting in severe coughing.
This may progress to include: Loss of ability to form lip seal,
chew, propel food with the tongue and/or form a bolus; Poor
or absent swallow reflex; Weak pharyngeal muscles resulting
in uncoordinated swallow; Failure to close airway; Muscle
spasm; Acid reflux.
Resulting in Drooling; Dehydration and weight loss;
Aspiration and recurrent chest infection; Impaired respiratory
function.
1.Food textures (SALT)
2.Fortification (Dietetics)
3.Head positioning and support (Physio)
4.Timing and quantity of food
5.Enteral feeding (PEG; RIG): can be used in combination
with oral feeding; patient’s wishes should be sought at an
early stage; (risks higher when illness progressed; weight
loss affects prognosis)
6.Drooling/constipation (Prescribing)
Thin, runny saliva:
Suction
Tricyclic antidepressants such as: Amitriptyline
Hyoscine (butylbromide or hydrobromide)
sublingually, S.C., 24 hour syringe pump; Transdermal patches
Glycopyrronium (Robinul)
(usually given PO or S.C. as intermittent injections or via a syringe pump).
Botox injection
Attention to head support and general posture - consult physiotherapist or
OT.
Thick tenacious saliva:
Check fluid intake, re-hydrate, avoid mouth breathing. Oral hygiene
- consult district nurse.
Proteases such as Papain or Bromelaine, from health food stores
sprinkled on the tongue can help break down thick saliva.
Pineapple, papaya, apple or lemon juices or flavoured ice cubes
can also help.
Nebulise: saline
Mucodyne (Carbocysteine)
Expectorants (e.g.)Robitussin
Tends to be due to forced inactivity, reduced peristalsis, low fluid intake,
reduced fibre intake and/or weakness of pelvic floor/abdominal muscles, and
use of analgesics.
Maintain hydration and fibre intake.
Treatment
Regular aperients:
Movicol sachet
Lactulose
Docusate
Sennoside B
Co-danthramer (where prognosis is limited).
Use of suppository, enemas, manual evacuation may be necessary on
occasions.
Also remedies such as bulking agents, prunes, linseed etc. available over the
counter.
Note: Diarrhoea may be due to constipation with overflow.
Major cause of anxiety.
Always review swallow
May lead to:
• Fear, anxiety, panic & disturbed sleep;
• Fatigue and reduced functional ability;
• Daytime somnolence;
• Poor appetite;
• Vivid Dreams; Breathless with or without exertion;
• Breathless when lying (orthopnoea);
• Hypoxia or hypercapnia and possible confusion;
• Inability to expectorate lung secretions.
• Increased CO2 levels resulting in headaches, particularly on
waking. Caution: O2 should be prescribed by specialist and used
with caution (hypercapnia: use 28% O2 only until specialist
assessment)
Consider:
• Referral to a consultant in respiratory medicine early on, to
explore options before respiratory problems become evident.
• Involve the family;
• Assisted ventilation;
• Consider annual flu vaccination.
• Referral to the palliative care team;
• Medication Use : Humidifier; Nebuliser;
• Low dose beta blockers e.g. Metoprolol, Propranolol, to reduce
production of lung secretions and thick tenacious saliva, mucus
plugs (contra-indicated in asthmatics);
• Carbocisteine – increase mucodyne to relieve symptoms – use
with caution as patient’s cough is weak; Midazolam S.C. or
buccal; Lorazepam; Diazepam;
• Liquid morphine; Morphine Sulphate modified release tablets e.g.
MST, Zomorph; Diamorphine.
At each contact with the patient assess their breathing and ask
about symptoms (as below).
Early referral to a respiratory specialist is vital if one or more of the
following occur.
o

Benefits
 Improved quality of life through improved sleep, less troublesome
symptoms during the day;
 Increased survival;
 Increased appetite.
Disadvantages
 Risk of aspiration if control of oropharyngeal secretions is poor;
 Skin breakdown if mask is used for long periods;
 Inability to tolerate mask or use machine;
 Less effective as MND progresses;
 Increasing dependency over time, which may have inverse impact on
quality of life;
 Usually requires assistance of a carer and can increase the carer burden.
o
Affects round half of sufferers
o
High index of suspicion. May lead to agitation or
restlessness.
o
Muscle spasm, neuropathic pain, joint pain, immobility,
constipation or colic
o
Often requires a combination of agents
o
Re assess and adjust management often.

Significant issue for some but may be subtle.

Fronto temporal cognitive loss (loss of inhibition,
rigidity, repetitive behaviour) affects 15% or more;
changes may be mild.

Behavioural or mild personality change commonly
reported.






Key issue
Major and progressive losses
Feelings of helplessness common
Fear of choking causes great anxiety
Watch for depression
Anticipate carer exhaustion and advise re self
care.

Is someone helping the patient develop an advance care plan?
Do you need to involve a specialist palliative care service?
Have you discussed the situation with patient and family so they can
prepare for what is likely to happen?
Have you continued to reassure the patient and family that, contrary
to popular belief, death by choking or fighting for breath is not the
norm?
Have you arranged for appropriate medications for the home to
prevent a crisis admission?
Is there adequate physical and emotional support for the family if
the person wishes to die at home?
Have you informed the ambulance service of any relevant advance
planning, e.g. DNACPR?
Have you informed your local primary care out-of-hours service?
