Aged 50 years and over are affected in 1 %, this number increased in 10 % in person 60 years and over about 1½ times more common in men than in women. The causes of Parkinson's disease (PD), the second most common neurodegenerative disorder, are still largely unknown. Current thinking is that major gene mutations cause only a small proportion of all cases and that in most cases, non-genetic factors play a part, probably in interaction with susceptibility genes. Numerous epidemiological studies have been done to identify such non-genetic risk factors, but most were small and methodologically limited. Larger, well-designed prospective cohort studies have only recently reached a stage at which they have enough incident patients and person-years of follow-up to investigate possible risk factors and their interactions.

He is today looking for medical advice after has been notice a little resting tremor in both hands more marked in right hand, also noted slow motion in some movement mainly with changes of position and some incoordination when he walks. He is concerned because his paternal Grandfather died after suffering for many years with Parkinson’ s disease related disabilities, his father died at 43 years old in a motor vehicle accident and no time to development the disease and he hears that Parkinson’s Disease has some genetics implication. His medical history is only remarkable for a 10 years history of well controlled High Blood Pressure and not remarkable Family History except for what we mention before.

He is happily married for 25 years and has 2 healthy sons studying in college for whom he is worried too in case that this has some degree of genetics transmition. 7 Physical Examination Weight: 187 p0unds Height 5’11†BMI: 26.1 Temp: 97.9 f PULSE: 76 RESPIRATION: 18 BP: 125/ 75 MMHG Physical Exam: General Appearance: Healthy appearing adult male in no acute distress.

We can diagnose Parkinson's disease based on your medical history, a review of signs and symptoms, and a neurological and physical examination. may suggest a specific single-photon emission computerized tomography SPECT scan called a dopamine transporter (DAT) scan.

Although this can help support the suspicion that you have Parkinson's disease, it the symptoms and neurologic examination that ultimately determine the correct diagnosis. Most people do not require a DAT scan. We can order too blood tests, to rule out other conditions that may be causing the symptoms. Imaging tests — such as MRI, CT, ultrasound of the brain, and PET scans — may also be used to help rule out other disorders. Imaging tests aren't particularly helpful for diagnosing Parkinson's disease.

In addition to the examination, we can prescribe carbidopa-levodopa (Rytary, Sinemet, others), a Parkinson's disease medication, and must be given a sufficient dose to show the benefit, as low doses for a day or two aren't reliable. Significant improvement with this medication will often confirm your diagnosis of Parkinson's disease. Sometimes it takes time to diagnose Parkinson's disease. we may recommend regular follow-up appointments with neurologists trained in movement disorders to evaluate your condition and symptoms over time and diagnose Parkinson's disease. Treatment Lifestyle modification: Healthy eating Exercise Avoiding falls Daily living activities Medications: Carbidopa-levodopa MAO inhibitors ((Eldepryl, Zelapar), rasagiline (Azilect) and safinamide (Xadago) Catechol O-methyltransferase (COMT) inhibitors (Entacapone) Anticholinergics. (benztropine (Cogentin) or trihexyphenidyl.) Surgical procedures Deep brain stimulation 12 Prognosis: Risk of Dementia Mortality Risk Especially patients with Parkinson disease who carry an APOE ε2 allele have an increased risk of developing dementia.

Increased mortality risk in Parkinson disease is dependent on disease duration and is only modest in the absence of dementia. The prevalence of Parkinson disease (PD), the second most common neurodegenerative disorder, is expected to increase as populations worldwide age. Insight into the prognosis is therefore desirable. Parkinson disease has been associated with an increased risk of developing dementia and a reduced life expectancy. references Giesbergen, PC,. MCHofman, AKoudstaal PJBreteler.

Parkinson’s Disease: Laboratory for Diagnosis, Symptom, and Illness Management

Patient Overview

Patient Name: Luis Morel
Age: 62 Years
Gender: Male
Ethnicity: Hispanic
Marital Status: Married
Allergies: Seafood
Chronic Illnesses: Controlled Hypertension
Hospitalizations/Surgeries: Inguinal Hernia (2 years ago)
Immunization Status: Updated (PCV13, Influenza, RZV)

Epidemiology of Parkinson’s Disease

Parkinson's disease (PD) affects approximately 1% of the population aged 50 years and older, with a significant increase to over 10% in individuals aged 60 and above (Giesbergen et al., 2015). Although PD primarily presents in individuals over 40, juvenile Parkinsonism has been reported in rare cases. Epidemiological studies suggest that the incidence and prevalence of PD exhibits geographic variations, which may be attributed to both genetic and environmental factors (Ruitenberg et al., 2011).

Etiology and Pathophysiology

Parkinson's Disease can be subdivided into three classifications: primary (idiopathic), secondary (parkinsonism due to external factors), and familial (genetic predispositions affecting approximately 20% of cases). The primary form remains the most common and is characterized by unknown origins and not linked to identifiable stimuli (Wooten et al., 2004). The neurodegeneration observed in PD is primarily due to the loss of dopaminergic neurons in the substantia nigra, leading to a reduction in dopamine levels and resultant motor and non-motor symptoms (Kalia & Lang, 2015).

Risk Factors

Several risk factors for developing PD include:
- Heredity: Family histories of PD increase the risk, particularly if first-degree relatives are affected.
- Age: The likelihood of developing PD increases significantly after age 60.
- Sex: Men exhibit a higher incidence rate than women.
- Environmental factors: Exposure to certain toxins and chemicals may elevate risks (Prasad et al., 2021).

Clinical Presentation

Patient History:
Mr. Morel, a 62-year-old Hispanic male, presented concerns of resting tremors in both hands, particularly the right, along with bradykinesia and some gait instability. His paternal grandfather’s history of PD raises the patient’s concern regarding potential genetic implications for his sons.
Physical Examination:
- Weight: 187 pounds
- Height: 5’11”
- Vital Signs: BP 125/75 mmHg, Pulse 76, Temperature 97.9°F
- Notable findings included resting tremors, rigidity in all extremities, postural instability, and slowed movements.

Differential Diagnosis

It is important to rule out other neurologic and non-neurologic disorders which may present similarly, such as:
- Spinocerebellar ataxia
- Huntington's disease
- Essential tremor
- Depression and other psychiatric conditions (Zhang et al., 2021)

Diagnosis

No definitive tests exist solely for diagnosing PD, and it primarily relies on medical history, symptom review, and neurological examinations. Supportive diagnostic tools include dopamine transporter (DAT) scanning (Kalia & Lang, 2015). Blood tests and imaging modalities like MRI or CT scans may provide additional information to exclude other conditions but are not diagnostic for PD (Martinez et al., 2019).

Management Strategies

Lifestyle Modifications:
Encouraging balanced nutrition, regular exercise, and fall prevention strategies are critical for Mr. Morel's management (Miller et al., 2018).
Medications:
First-line dopaminergic therapy includes Carbidopa-levodopa (Sinemet), which aims to replenish dopamine levels in the brain. Other adjunct medications include MAO-B inhibitors like Rasagiline, COMT inhibitors such as Entacapone, and anticholinergics for managing specific symptoms (Blandini et al., 2016).
Surgical Procedures:
Deep brain stimulation (DBS) may be considered for patients who do not respond adequately to medications, particularly in later stages of the disease (Katzenschlager et al., 2007).

Prognosis

Patients with PD experience elevated risks of both dementia and early mortality. This risk is particularly pronounced in patients who are APOE ε2 allele carriers (Holt et al., 2016). PD is progressive; therefore, regular follow-ups with specialized neurologists are essential for managing disease progression and related complications effectively.

Conclusion

In summary, Parkinson’s Disease remains a complex and multifactorial neurodegenerative disorder that necessitates a multidisciplinary approach for optimal patient management. Decision-making through robust diagnosis, timely intervention strategies, and personalized management plans ensures improved quality of life and functional capacity for patients like Luis Morel.
