Urinary symptoms are very common in Parkinson's disease (PD). They are primarily irritative (frequency, urgency, urge incontinence) and correlate with the urodynamic finding of involuntary detrusor contractions at early stages of bladder filling (detrusor hyperreflexia). Obstructive symptoms (hesitancy, weak urinary stream) may be seen in a smaller number of patients by themselves or combined with irritative symptoms. They may be secondary to anticholinergics, obstructive uropathy, or point to the presence of multiple system atrophy. Dysfunction of the striated urethral sphincter and pelvic musculature can be seen in variable numbers in PD, with the main abnormality that of delayed relaxation at the time of initiation of voluntary voiding.

We discuss two types of age-associated diseases; aging-dependent such as Alzheimer's disease and congestive heart failure which increase logarithmically with age, versus age-dependent such as multiple sclerosis and amyotrophic lateral sclerosis which occur at proscribed ages, and then occurrence of new cases ceases or diminishes with further aging. Prevention strategies with both types emphasize postponement or delay of onset. The non-fatal aging-dependent diseases and conditions are an accumulating burden as we age, and increase overall morbidity in late years. These include Alzheimer's disease and other dementias, Parkinson's disease, loss of vision and hearing, incontinence, osteoporosis and hip fracture, osteoarthritis and depression. With mortality postponed, we will be living for many years at old and vulnerable ages. Life's quality will be reasonable for most. Still, increasing the chance that all will experience this desirable outcome requires pursuing the means to delay the onset of the physical and social events which we categorize as the non-fatal aging-dependent diseases and conditions. We must recognize that each added year occurs at the tip of an exponential curve where risk is maximal.

Although patients with Parkinson's disease (PD) experience pelvic organ dysfunction of the urinary bladder, bowel and genital organs, an accurate incidence of the dysfunction and its characteristics have yet to be ascertained. We devised a detailed questionnaire on these three pelvic organ functions in PD patients and control subjects, in our search for a hallmark that would distinguish between the two groups. The PD group comprised 115 patients; 52 men and 63 women, age range 35-69 (average 59) years old, average duration of illness 6 years, median Hoehn and Yahr stage 3. All were taking levodopa with/without dopamine agonists. The control group comprised 391 local individuals who were undergoing an annual health survey; 271 men and 120 women, age range 30-69 (average 48) years old. The questionnaire had three parts: bladder (nine questions), bowel (four questions), and sexual (three questions for women, five for men) function. Each question was scored from 0 (none) to 3 (severe) with an additional quality of life (QOL) index scored from 0 (satisfied) to 3 (extremely dissatisfied). The completion rate was 100% for bladder and bowel functions, whereas for sexual function, it was 95% (control) and 88% (PD) for men and 82% (control) and 60% (PD) for women. As compared with the control group, the frequency of dysfunction in the PD group was significantly higher for urinary urgency (women 42%, men 54%), daytime frequency (28%, 16%), nighttime frequency (53%, 63%), urgency incontinence (25%, 28%), retardation (44% of men), prolongation/poor stream (men 70%), straining (women 28%); constipation (63%, 69%), difficulty in expulsion (men 57%), diarrhea (men 21%); decrease in libido (84%, 83%), decrease in sexual intercourse (55%, 88%), decrease in orgasm (men 87%), and in men, decreases in erection (79%) and ejaculation (79%). The QOL index for the PD patients was significantly higher for bladder (27%, 28%) and bowel (46%, 59%) but not for sexual dysfunction, despite the group's high prevalence of sexual dysfunction. In the PD patients, fecal incontinence was associated with urinary incontinence. Stress urinary incontinence and a decrease in libido were more common in women than in men. Bladder and bowel dysfunction, but not sexual dysfunction increased with the Hoehn and Yahr stage. Sexual dysfunction, but neither bladder nor bowel dysfunction, increased with age. Patients taking levodopa and bromocriptine more frequently had bladder (voiding phase) dysfunction than those taking levodopa only. The findings show that bladder, bowel and sexual dysfunction are all prominent in patients with PD. Amelioration of pelvic organ dysfunction, particularly bowel dysfunction which most affects the quality of life, therefore should be a primary target in the treatment of patients with PD.

This study aimed to determine final year medical students' knowledge and perception of physiotherapy services within South Australia, and to identify any need for further education about physiotherapy within the undergraduate medical course. A survey of medical students at two universities found that physiotherapists enjoyed a positive reputation, especially when compared with alternative health practitioners. Although general knowledge was high, medical students were largely unaware that physiotherapists work in occupational health settings and offer treatments for Parkinson's disease, incontinence and headaches. The medical students had received little formal education about physiotherapy throughout their undergraduate course and clinical experience had been their major source of information. The findings suggest that medical students need more information about physiotherapy services.

Direct and indirect signs and symptoms of Parkinson's disease are a major cause of disability in the elderly. Intrinsic symptoms comprise not only the well-known clinical hallmarks of this disease with motor behavioral abnormalities, such as bradykinesia, hypokinesia, rigidity and tremor, but also autonomic failure with orthostatic hypotension, urinal incontinence and impotence as well as non-motor behavioral abnormalities: mental dysfunction characterized by mood disorders, cognitive dysfunction and, sporadically, delusions and hallucinations. These symptoms are caused by a progressive abnormal degeneration of the dopamine (DA) producing cells in the substantia nigra (SN) and ventral tegmentum area (VTA) in combination with an interindividual fluctuating degree of decay in the noradrenergic (locus coeruleus), cholinergic forebrain (nucleus basalis of Meynert) and serotoninergic (dorsal raphe nuclei) systems. Extrinsic symptoms, induced by pharmacotherapy, mainly manifest with (un)predictable motor response fluctuations and dopaminomimetic psychosis. Psychological and psychiatric symptoms in Parkinson's disease (PD) are important predictors of the patient's quality of life. As these symptoms are potentially treatable, identification is of major clinical importance both for the patients and their caregivers and may enable to maintain Parkinson's disease patients at home for a longer period.

The objective of this work was to determine the predictors of depressive symptoms among spouse caregivers of Parkinson's disease (PD) patients. Little is known about the strain in giving care to PD patients and how the motor, cognitive, and behavioral complications of PD contribute to depression among spouse caregivers. Forty-five consecutive PD patients and their spouse caregivers agreed to be evaluated after a routine clinic visit. Patient demographic data and the presence of hallucinations, delusions, incontinence, and sleep disturbances were obtained. The patients were assessed using the Unified Parkinson's Disease Rating Scale (UPDRS-motor section), Hoehn and Yahr (H&Y) staging, and the Mini-Mental State Examination (MMSE). Depressive symptoms were assessed using the 17-item Hamilton Depression Scale (HAMD-17) and the Beck Depression Inventory-II (BDI-II) on patients and spouses. Thirty men and 15 women had a mean age of 71.5 years (range 53-85), average PD duration of 10 years (range 1-26), a mean "on" H&Y stage of 2.8 and an MMSE mean score of 26 (range 13-30). There was good correlation between the HAMD-17 and the BDI-II scores in both patients (r = 0.69, P = 0.001) and spouses (r = 0.66, P < 0.001). A moderate correlation was noted between the spouse HAMD-17 score and the patient UPDRS-motor score (r = 0.34; P = 0.02), the age of PD onset (r = 0.33; P = 0.02) and patient HAMD-17 scores (r= 0.29; P = 0.05). A stronger correlation was noted between spouse HAMD-17 scores and the years of PD duration (r= 0.43; P = 0.003). There was a significant difference in the mean spouse HAMD-17 scores among PD patients with sleep disturbances versus those who did not (10.2 vs. 6.4; P = 0.04). However, on stepwise regression analysis, only the duration of PD remained significant (adjusted r = 0.17; P = 0.003). No difference was noted with hallucinations, delusions or incontinence. We concluded that the duration of PD appears to be the strongest predictor of depressive symptoms among spouse-caregivers in this small cohort.

Urinary dysfunction in idiopathic Parkinson's disease (IPD) has already been described, however its incidence, urodynamic pattern, dependence on the severity of parkinsonism as well as improvement with levodopa treatment are not exactly known. The aim of the study was to evaluate the frequency of urinary disturbances in patients with idiopathic Parkinson's disease and their relationship to treatment with levodopa. The investigation was carried out on 41 IPD patients aged 37-84 (mean 61.6) years. The neurological examination, including evaluation of parkinsonism according to UP-DRS scale was conducted together with the urological tests, including uroflowmetry and cystometry. Patients with infection of the urinary tract and with prostate hypertrophy were excluded from the study. 32 (78%) patients had urinary symptoms: frequency in 27 cases (65%), urgency in 9 cases (21%), urge incontinence in 1 case and dysuria in 1 case. Disorders in urodynamic examination were found in 26 cases (63%); they were: detrusor hyperactivity in 21 cases (51%), prolonged time of micturition in 18 cases (44%) and decrease of maximum flow rate in 19 cases (46%). Detrusor hyperactivity was more frequent in patients with extended parkinsonian motor signs. The results of the examination indicate frequent urinary disturbances (70%) in IPD, which improve during treatment with increased dose of levodopa.

PROBLEMS OF THE PROSTATE: Benign hypertrophy of the prostate (BHP), when it occurs, is manifested by an obstruction or irritation related to overactivity of the bladder. The obstructive syndrome is defined by urodynamic tests. Urge incontinence and study of the pressure-flow ratio are the tests of choice. The functional handicap and impact on quality of life are assessed using the International Prostatism Symptoms Score (I-PSS). Efficient and fairly well tolerated medical treatment has reduced the indications for surgery. It relies on alpha-blockers, 5a-reductase inhibitors and phytotherapy. When indicated, the surgical treatment of choice is endoscopic resection of the prostate. Among the non-prostatic micturition disorders, urge micturition with, in extreme cases, incontinence are due to detrusor instability. This is of multifactor origin; enhanced by the local irritation or environmental factors, it usually occurs within a context of acute or chronic pathologies. Treatment is recommended with anticholinergic agents. New molecules have recently been launched, better tolerated than oxybutinine. Electrostimulation can be a good alternative in mentally normal patients. Micturition due to excess urine may be due to overactivity of the bladder, the major risk of which is acute urine retention. It can also be observed during neurological affections such as Parkinson's disease or during administration of certain drugs. Nocturnal polyuria is a frequent problem. However, simple hygiene and dietary measures and the control of certain concomitant diseases can usually relieve the symptoms. Medical treatment relies on desmopressine.

Vascular parkinsonism has not been well defined and the clinical correlation of vascular parkinsonism is still not clear. The aim of the study was to estimate prevalence of occurrence of vascular parkinsonism, analysis of risk factors leading to its development and to identify clinical features that suggest a vascular origin. 214 patients with Parkinson's disease were examined. Their ages ranged from 37 to 88 years (median 66.4 years). Evidence of vascular parkinsonism was assessed using a vascular rating scale previously described by Winikates and Jankovic. Statistical analysis was performed with Mann-Whitney U test, chi 2 Pearson test, chi 2 Yates test, Spearman rank correlation and Student's t test. Out of 214 patients 8 were proved to have developed Parkinson's disease due to vascular disease, what gave 3.74%. Out of risk factors for stroke 5 patients had hypertension, 3 had diabetes mellitus, 2 suffered from heart disease, 2 had infarctus myocardii, 1 had hyperlipidemia, 1 had atrial fibrillation. Additionally, those patients had neuroimaging (CT or MRI) evidence of vascular disease in one or more vascular territories. Patients with vascular parkinsonism were older, had shorter duration of disease, were more likely to present rigidity rather than tremor. Dementia and incontinence were more common in vascular group than in Parkinson's disease group. Patients with vascular parkinsonism were also significantly more likely to have corticospinal findings. Proving that Parkinson's disease had vascular etiology is extremely difficult. The test results are inconclusive.

Urinary symptoms are prevalent in the geriatric population.Symptoms, however, often are misleading. Urodynamic evaluation can help target specific treatments of specific disorders. In this article, the fundamentals of urodynamics are described. In addition,urodynamic findings in common geriatric conditions, such as Parkinson's disease, cerebral vascular accidents, benign prostatic hypertrophy, and incontinence, are discussed.
