Treatment for Disease Modification in Chronic Neurodegeneration

Winslows Vey 18, 5000 Odense, Denmark * Correspondence: [email protected] Abstract: Symptomatic treatments are available for Parkinson’s disease and Alzheimer’s disease. An unmet need is cure or disease modification. This review discusses possible reasons for negative clinical study outcomes on disease modification following promising positive findings from experi- mental research. It scrutinizes current research paradigms for disease modification with antibodies against pathological protein enrichment, such as α-synuclein, amyloid or tau, based on post mortem findings. Instead a more uniform regenerative and reparative therapeutic approach for chronic neurodegenerative disease entities is proposed with stimulation of an endogenously existing repair system, which acts independent of specific disease mechanisms. The repulsive guidance molecule A pathway is involved in the regulation of peripheral and central neuronal restoration. Therapeutic antagonism of repulsive guidance molecule A reverses neurodegeneration according to experimental Citation: Müller, T.; Mueller, B.K.; outcomes in numerous disease models in rodents and monkeys.

Association Between a Null Mutation in the Human Ciliary Neurotrophic Factor (CNTF) Gene and Increased Incidence of Psychiatric Diseases?
ELSEVIER Neuroscience Letters 203 (1996) 109-110 Association between a null mutation in the human ciliary neurotrophic factor (CNTF) gene and increased incidence of psychiatric diseases? Johannes Thome a,*, Johannes Kornhuber a, Alessandra Baumer b, Michael R6sler a, Helmut Beckmann a, Peter Riederer a aDepartment of Psychiatry, University of Wfirzburg, Fiichsleinstrafle 15, 97080 Wfirzburg, Germany blnstitute of Human Genetics, University of Wfirzburg, Am Hubland, 97074 Wiirzburg, Germany Received 16 October 1995; revised version received 6 December 1995; accepted 6 December 1995 Abstract We report a possible association between a null mutation in the human ciliary neurotrophic factor (CNTF) gene and psychiatric dis- eases. Prior findings that the mutant allele frequency is not significantly elevated in patients suffering from neurological diseases are confirmed. The frequency of the mutant allele was higher among psychiatric patients (0.192, n = 297) than among healthy controls and neurological patients (0.142, n = 267). This difference (one-tailed 2 x 2 chi-square test, P < 0.05) might be evidence that disturbances in the neurotrophic factor system could play a crucial role in the etiopathogenesis of psychiatric disorders, mainly psychoses.

To deﬁ ne a practice guideline for biological treatment of dementia and to make transparent the development of the guideline connecting the original data with the resulting recommendations. Methods. This guideline includes pharma- cologic treatment considerations for patients with Alzheimer’s disease, vascular dementia, DLB, and fronto-temporal dementia. Studies were selected that represent double-blind placebo-controlled trials of at least 3 months duration in patients with a diagnosis of dementia according to accepted international diagnostic criteria (for example the NINCDS/ ADRDA or NINDS/AIREN criteria). Moreover, to be included studies had to fulﬁ ll a restrictive set of methodological criteria. Original studies and not meta-analyses determined the evaluation and the development of recommendations. Results. Antidementia pharmaceuticals neither cure nor arrest the disease.
