2 Aims Prevalence Diagnosing Non Motor symptoms Stages of PD Treatment
Patients experience

3 Prevalance 1 in 500 UK resident have PD 1 in 100 > 60 yrs have PD
Pt have formal PD diagnosis (GPRD database) 1 in 20 Pt; Develop symptoms under 40 yrs of age By 2020: PD no will rise 28% rise in PD cases Economic burden of PD is ~ £2 billion annually (Imperial College) (1, 2)

4 Diagnosing PD A set of characteristic symptoms that affect motor control: resting tremor, bradykinesia, and hypertonia. Resting tremor is an oscillating movement (4—6 Hrzd) that occurs when the patient is trying to be still; disappears on action Essential Tremor: Persists on movement Cerebellar Tremor: Intentional tremor

5 Bradykinesia means slowness of movement.
Usually experienced as ‘weakness’ or ‘stiffness’ of limb Hypertonia means excessive muscle tone. Manifest itself as rigidity or stiffness. Other typical features: are a Stooped posture/ Slow, shuffling festinant gait/ Reduced arm swing/ Facial appearance (Masked like ‘hypomimia’)/ Low volume speech/ Excessive drooling of saliva

6 The ‘Braak hypothesis’
Stage 5 and 6: Changes spread to the cortex Stage 3 and 4: Pathology spreads to the midbrain and basal ganglia Stage 1 and 2: Pathology confined to certain structures in the brain stem, not yet the substantia nigra Neurodegeneration happens elsewhere in the brain in Parkinson's, and may precede damage to the substantia nigra. The neuropathologist Braak has suggested that pathological changes which occur in Parkinson's can be divided into six stages – The ‘Braak hypothesis’ 13 Braak has suggested that the condition may begin in the olfactory bundle and lower brainstem, and studies are underway to detect Parkinson’s disease at a premotor phase.16 As illustrated in the slide This may explain the onset of sleep disturbance and loss of sense of smell prior to the onset of motor symptoms, as well as other ‘non-motor’ symptoms of Parkinson's.13 Image adapted from The Professionals Guide to Parkinson’s Disease, Parkinson'sS 6

7 Non-motor symptoms of PD 3
Neuropsychiatric Autonomic Sleep disturbance Sensory symptoms Dementia Depression Apathy Anxiety Loss of libido REM sleep disorder RLS Vivid dreams Daytime somnolence Dystonia Constipation Urinary incontinence Erectile dysfunction Excessive sweating Postural hypotension Excessive salivation Pain Paraesthesia Non-motor symptoms are a common source of disability in PD. Many patients do not spontaneously volunteer information about these symptoms, specific questions about them should be part of routine assessment. The Non motor symptom questionnaire is used for patients to self report.26 Dementia: When dementia develops more than one year after the onset of the motor features of PD, it is defined as ‘Parkinson’s Disease with Dementia’ (PDD). When it develops within a year it is defined as ‘Dementia with Lewy Body’ (DLB).27 They present with decline in visuospatial abilities, category learning, verbal fluency, set switching and executive function, rather than the memory loss seen in Alzheimer's. There is evidence of spontaneous hallucinations and psychosis, which maybe worsened by dopaminergic drugs or systemic illness such as infection. 28 Depression: Depression is a major clinical problem in patients with PD. It affects around 40% of patients with PD and leads to significant reduction in quality of life. Clinicians and nurses should have a low index of suspicion for depression in PD. Constipation: Constipation is extremely common, if not universal, in PD. It can even occur before the onset of the motor disorder. It is probably caused by direct involvement of the myenteric plexus in the pathology of the condition as lewy bodies are found in the gut wall. Sleep disorders: Sleep disturbance occurs in nearly all patients with PD. Patients should be asked about sleep problems regularly and, if present, a thorough sleep history should be taken.27 Of the 13,000 respondents from the PDS members survey 34% reported that they were getting a good nights sleep and 80% regarded it as very important.24 Up to 98% of patients with PD report sleep disturbances.25 Dystonia: Dystonia often occurs in the early hours of the morning and is a common reason for disturbed sleep in patients with PD.30

8 Parkinson's Disease Criteria for entry into staging categories
Diagnosis / early Knowledge of disease Ideas and perceptions Employment issues Neuro rehab Levodopa or Dopamine agonists Rasagiline. selegiline Maintenance Promote normal function Regular reviews-red flags Support MDT input Entacapone Stalevo Complex Motor complications. Neuropsychiatric complications Reduction of drugs. Carer support/respite/hospice Amantadine. Apomorphine Duodopa DBS Managing PD is a complex process due to the range of symptoms, rate of progression and range of treatment options This 'Pathways Paradigm' was developed by MacMahon and Thomas (1998), ‘to improve the prognosis and reduce the impact of this [Parkinson's] disease on patients and their caregivers (1) It is now the most accepted paradigm for PD and comprises four stages: diagnosis, maintenance, complex and palliative Each stage, although by necessity relatively flexible, represents a specific area for clinical management for the disease duration Palliative Symptoms versus side effects Advanced care needs 4 .MacMahon D.G Thomas.S Practical Approach to Parkinson’s Disease. Journal of Neurology (1998) 245 (SUPP1)S19.S22

9 Patient education.MDT input
TREATMENT Begins with Diagnosis Patient education.MDT input Discussion of when and which drug Treatments. Bradykinesia dominated disease may need earlier treatment than tremor dominated disease People with suspected Parkinson’s should be referred quickly and untreated to a specialist (NICE 2006)

10 Drug classes in Parkinson’s
Levodopa DAs Dopamine agonists MAO-B inhibitors Monoamine oxidase B inhibitors COMTs Catechol-O-methyltransferase inhibitors Anticholinergics

11 Drugs to avoid Generic name Brand name Usually prescribed for
prochlorperazine metoclopramide Stemetil Maxalon Dizziness, nausea and vomiting fluphenazine perphenazine flupentixol Motival Triptafen Fluanxol Depixol Depression chlorpromazine haloperidol Largactil Moditen Serenace Haldol Fentazin Confusion, hallucinations, disorientation, or disturbed thinking All of these drugs, block dopamine receptors in the brain. The only anti emetic that can safely be taken is domperidone as it does not cross the blood brain barrier. New atypical neuroleptic’s decrease the risk of aggravating Parkinson’s symptoms.35

12 Drug management As responses to drugs are variable, treatment regimes differ from person to person The timing of drugs is important in order to achieve continuous dopaminergic stimulation Nurses have a key role in helping the patients manage complex drug regimes Sudden discontinuation of treatment should be avoided as it can result in Neuroleptic Malignant Syndrome. Get it on time campaign. NH homes to send in medication with patient To achieve the right balance between benefit and any side effects, the individual will need to understand and be involved in which drugs are being used and why drug timing is so important. Neuroleptic malignant syndrome is a rare, life-threatening reaction in people exposed to neuroleptic medication. It can also occur in Parkinson’s patients after sudden withdrawal of anti-Parkinson's drugs. It is characterised by hyperthermia, muscle rigidity, altered levels of consciousness, autonomic instability and elevated serum creatine kinease (CK) level. Therefore anti-Parkinson’s medication should not be withdrawn abruptly or allowed to fail suddenly due to poor absorption (e.g. gastroenteritis, abdominal surgery)35

13 End note Start ‘slow and low’
Watch for side effects; low BP, Orthostatic hypotension, ICD NMS are more common in older pts NMS are often confusing & poorly recognised Insomnia: likely due to Akathisia (inner restlessness), stiffness (rigidity), difficulty turning in bed, as well as tremor Anxiety: likely due to Akathisia Cramps: could be ‘dystonias’: inspect feet for inversion, great toe Pain/ Paresthesia/ depression: may be levodopa responsive Avoid hospitalisation The patient is the expert
