Abstract
Parkinson’s disease is a neurodegenerative disorder caused by loss of dopamine neurons in the substantia nigra pars compacta. Tremor, rigidity, and bradykinesia are the major symptoms of the disease. These motor impairments are often accompanied by affective and emotional dysfunctions which have been largely studied over the last decade. The aim of this study was to investigate emotional processing organization in the brain of patients with Parkinson’s disease and to explore whether there are differences between recognition of different types of emotions in Parkinson’s disease. We examined 18 patients with Parkinson’s disease (8 men, 10 women) with no history of neurological or psychiatric comorbidities. All these patients underwent identical brain blood oxygenation level-dependent functional magnetic resonance imaging for emotion evaluation. Blood oxygenation level-dependent functional magnetic resonance imaging results revealed that the occipito-temporal cortices, insula, orbitofrontal cortex, basal ganglia, and parietal cortex which are involved in emotion processing, were activated during the functional control. Additionally, positive emotions activate larger volumes of the same anatomical entities than neutral and negative emotions. Results also revealed that Parkinson’s disease associated with emotional disorders are increasingly recognized as disabling as classic motor symptoms. These findings help clinical physicians to recognize the emotional dysfunction of patients with Parkinson’s disease.

Abstract
A 69-year-old Japanese man with a history of suprasellar surgery and irradiation developed bradykinesia and mild fatigue without muscle weakness, myalgia, pyramidal or extrapyramidal signs, parkinsonian symptoms, or ataxia. An endocrinological work-up revealed anterior hypopituitarism associated with secondary adrenal insufficiency. Higher brain function tests indicated an impaired frontal lobe function. The patient's bradykinesia, fatigue, and frontal lobe dysfunction improved within 2 weeks after the initiation of corticosteroid replacement therapy. To our knowledge, this is the first reported case of adrenal insufficiency manifesting as non-parkinsonian bradykinesia. Physicians should consider reversible non-parkinsonian bradykinesia associated with frontal lobe dysfunction as an unusual manifestation of adrenal insufficiency.

Blood Oxygenation Level-Dependent Functional MRI of Early Evidences of Brain Plasticity after Hemodialysis Session by Helixone Membrane of Patients with Indices of Adrenal Deficiency. Ann Neurosci 2017; 24:82-89. [PMID: 28588363 DOI: 10.1159/000475897] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2016] [Accepted: 01/05/2017] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Various alterations of hypothalamic-pituitary-adrenal axis function have been described in patients with chronic renal failure. Nevertheless, controversial evidences were stated about the association between adrenal function deficiency (AD) and hemodialysis (HD). PURPOSE The goal of this paper was to estimate indirect indices of the adrenal gland dysfunction which is potentially influenced by oxidative stress (OS) that still generates brain plasticity and reorganization of the functional control. METHODS Two male patients undergoing HD by the synthetic Helixone membrane for more than 6 months at the HD Center of the University Hospital of Fez, Fez, Morocco, were recruited. They underwent identical assessment immediately before and after the full HD session; this consisted of a blood ionogram revealing rates of sodium and calcium, and brain blood oxygenation level-dependent functional MRI (BOLD-fMRI) using a motor paradigm in block design. RESULTS The blood ionogram revealed hypercalcemia and hyponatremia in both patients. Both biological assessment and BOLD-fMRI study results revealed a high level of OS that induced activation of a significantly large brain volume area suggesting the occurrence of possible brain plasticity and functional control reorganization induced by free radicals and enhanced by AD. CONCLUSION The occurrence of brain plasticity and functional control reorganization was demonstrated in both patients studied who were undergoing HD by BOLD-fMRI with a notable sensitivity; this plasticity is induced by elevated OS occasioned by HD technique itself and probably amplified by AD. Similar results were found in a previous study performed on the same patients undergoing HD by a polysulfone membrane.
