This study was conducted on 15 outpatients with idiopathic Parkinson's disease, 10 on chronic levodopa therapy and 5 drug free, all complaining of painful syndromes. We investigated the perceptive and pain thresholds and the threshold of polysynaptic components of the blink reflex in patients and 8 controls. Our data indicate that as regards the perceptive, pain and R2, R3 thresholds, patients with and without levodopa therapy do not differ significantly from controls.

Parkinson's disease has been studied in a community of Northern Norway. The main object of the study was to find the prevalence of the disease. The prevalence of Parkinson's disease was 133 per 100,000 population (men 113, women 134) and 189 adjusted to the total Norwegian population (both sexes). Prevalence increased with age in both sexes, especially after the 60th year. The average age at onset was 63.1 years (men 60.5, women 65.4 years). Tremor was present in 98% of the patients, hypokinesia in 78%, rigidity in 65%, all three in 56% and pain in 35%. The prevalence, sex distribution, and the age at onset is similar to that in other European and North American studies.

A number of patients with Parkinson's disease complain of severe and distressing pain. Many of them are referred for psychiatric or other inappropriate treatment. The key diagnostic clue to the origin of the pain is that in almost all cases it fluctuates in parallel with the motor changes associated with levodopa treatment. The nature of this temporal association in the individual case, as well as aiding diagnosis, often indicates the need for appropriate modifications in antiparkinsonian therapy, which can be far more effective than conventional analgesic treatments.

Concentrations of putative neuroactive substances glutamate, aspartate, gamma-aminobutyric acid, glycine, proline and ethanolamine were determined in ventricular cerebrospinal fluid collected in patients suffering from Parkinson's disease, pain syndromes or cerebellar tremor. Values are similar to those given in the literature for lumbar cerebrospinal fluid. A decrease in gamma-aminobutyric acid in Parkinson patients, as reported in lumbar cerebrospinal fluid, could not be observed. Further evidence for a rostro-caudal gradient for gamma-aminobutyric acid is supplied. New insights into pathophysiological mechanisms in any of the investigated syndromes may not be derived.

Basic research helps to understand clinical knowledge which in turn leads to new fundamental research. Two examples are taken from the studies of the anomalies existing in the brain of patients suffering from Parkinson disease or deafferentation Pain. The researches performed to solve these two problems for the past 40 years (in particular by the author's working group) are replaced in the international context. In Man the precision of stereotaxic technique was improved by using the organisation of the somato-sensory thalamic projection described in animals by the physiologists. In the thalamus of Parkinsonian patients, the presence of cells bursting at tremor frequency led to search for the relations existing between the striato-nigral system and the motor thalamus. In the patients suffering from deafferentation Pain, a special role is attributed to the medial thalamus, whose characteristics were formerly studied in animals. The origin of the deafferentation Pain is nowadays studied in an animal model of this disease.

Madopar Hydrodynamically Balanced System (HBS), a new sustained-release levodopa preparation, was used to control severe nightly disabilities in 15 outpatients suffering from Parkinson's disease in an advanced state and with long-term levodopa therapy. This medication was given ante noctem in addition to an otherwise unchanged daily regimen of levodopa administration. In 13 patients a considerable diminution in nocturnal akinesia and in the frequency of waking up was reached with a mean dosage of 308 mg of Madopar HBS. Early morning akinesia was only slightly alleviated in four patients. The nocturnal off-period pain disappeared in one patient. Adverse effects consisted of nocturnal dyskinesia in two patients and early morning dystonia in another two patients. The regular use of sleeping pills was clearly reduced after Madopar HBS therapy.

The recent report by Madrazo and coworkers on the successful treatment of Parkinson's disease using adrenal medullary tissue transplanted to the caudate nucleus has aroused international interest in the procedure. The present article reports our initial experiences with the operation in five patients and discusses the postoperative effects of the procedure, the protocol used to monitor motor performance, and the need for cooperation with the two registries that have been created to follow morbidity, mortality, and efficacy. We intend to alert the neurosurgeon to important side effects, but not to assess the long term efficacy of the procedure. Postoperatively, a number of transient effects were seen in our patients, the most striking being somnolence, delusions, and lack of significant pain in spite of a large abdominal incision. The only complications have been respiratory. After the early postoperative period, gradual improvement of on-off times and Schwab-England disability scores was seen over 20 weeks. Long term cooperative studies are needed to demonstrate the efficacy of this procedure. neurosurgeons doing transplant operations are urged to join the registries so that uniform information can be collected.

In an open pilot study, 10 patients with Parkinson's disease and nocturnal and/or early-morning disabilities were given Madopar HBS (hydrodynamically balanced system; mean dose 250 mg) shortly before retiring in addition to their usual daytime antiparkinsonian treatment. Eight patients derived worthwhile improvement; the most gratifying responses were seen in the relief of nocturnal bradykinesia, rigidity and tremor. Early-morning symptoms were also improved in 3 out of 5 patients, possibly as a secondary response to an improved nights sleep. Cramps, early-morning dystonia and pain, however, responded poorly. Overall results are sufficiently encouraging to warrant further controlled studies with Madopar HBS in what has been a relatively neglected area of distress for many patients with Parkinson's disease.

We studied the prevalence and character of pain in Parkinson's disease (PD) and its association with motor fluctuations. Of 95 outpatients, 46% experienced pain they attributed to PD. Patients with pain were younger but no more disabled on objective motor scores than patients without pain. Musculoskeletal, dystonic, and joint pains were most frequent. Painful episodes, especially musculoskeletal cramps, usually occurred when parkinsonian disability was maximal.

The authors describe 5 patients with Parkinson's disease with coexistent sensory symptoms, mainly pains. In the light of the pertinent literature the authors regard pain as one of the symptoms in the parkinsonian syndrome. Diagnostic and therapeutic difficulties in this form of parkinsonism are stressed.
