Overview
Parkinson's disease is a degenerative movement disorder of the central nervous system. It is characterized by motor symptoms such as bradykinesia, rigidity, and tremor, but also cognitive and comunicative symptoms such as facial masking and dysarthria. These primary symptoms are the results of decreased stimulation of the motor cortex by the basal ganglia, normally caused by the insufficient formation and action of dopamine. Diagnosis is mainly clinical, it may be supported by MRI findings and dopamine transporter single-photon emission computed tomography (DaT SPECT), but definitive diagnosis is made by autopsy. The mainstay of therapy for motor symptoms of Parkinson disease are: Levodopa, dopamine agonists, monoamine oxidase (MAO) B inhibitors, anticholinergic agents, amantadine, catechol-O-methyl transferase (COMT) inhibitors, estrogen and other drugs such as Exenatide, uric acid, isradipine, nilotinib and GDNF infusion. Other therapies will depend on comorbidities.
Causes
Life Threatening Causes
Life-threatening causes include conditions that may result in death or permanent disability within 24 hours if left untreated.
- Parkinson's disease is not a life-threatening condition that may result in death or permanent disability within 24 hours if left untreated.
Common Causes
- The cause of Parkinson's disease is a dopamine depletion due to a necrosis of dopaminergic neurons in the substantia nigra.
- Factors that may contribute to the developement of Parkinson's disease are:
- Low norepinephrine levels
- The presence of Lewy bodies
- Autoimmune factors
Diagnosis
Shown below is an algorithm summarizing the diagnosis of Gait disturbance according to the American Academy of Neurology guidelines:[1]
Gait disturbance | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
When? | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Always with movement (may vary in severity) | Intermittently during movement (may vary in severity and frequency) | Continuous and intermittent disturbances are present at least once | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Continuous | Episodic | Mixed | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Transient inability to create effective stepping? | Unintentional increase in speed, usually with small steps? | Transient imbalance? | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Freezing | Festination | Disequilibrium | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Disequilibrium and hypermetria of stance and gait? | Associated with increased postural tone? | Slow or small steps and/or slow or small postural? | Involuntary movements? | Associated with muscle weakness or paralysis? | Static or axial postural deformities? | Secondary to musculoskeletal or central pain? | Present at a higher level? | Difficult to classify the continuous nature of the gait disturbance? | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Ataxic | Spastic | Bradykinetic/hypokinetic | Dyskinetic/Choreic/Dystonic | Paretic | Trunkal disturbance | Antalgic | Frontal disturbance | Undetermined | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
