Asymmetrical Parkinsonism
Dyspraxia
Cortical sensory deficit
Alien limb phenomenon
What are the gait abnormalities in IPD?
Camptocormia Difficulty initiating and stopping Small shuffling steps Loss of arm swing Freezing at obstructions
What are the facial abnormalities seen in IPD?
Reduced expression Reduced blinking Hypophonia Orofacial dyskinesia Blepharospasm
What are the non motor abnormalities seen in IPD?
Constipation Urgency Difficulty controlling saliva Sleep disturbance Low mode Anxiety
What is the treatment for IPD?
Levodopa
Decarboxylase inhibitors
E.g. Cobeneldopa
What can dopamine agonists be used for?
Delay use of l dopa
E.g. Ropinorole
What are the side effects of dopamine agonists?
Confusion
Hallucinations
Impulsive behaviour
What do COMT inhibitors do?
Prolong the effects of l dopa
E.g. Entacapone
What are MOAB inhibitors?
Alternative to dopamine agonists
E.g. Rasagaline
What are the stages of PD?
Pre diagnosis - no overt motor symptoms
Diagnosis - treatment commences, no complications
Complex - development of dyskinesia, cognitiv impairment, psychosis
Palliative - poor drug response, high complications
