Neurodegenerative diseases, including Parkinson’s disease (PD), are increasing in prevalence due to the aging population. Despite extensive study, these diseases are still not fully understood and the lack of personalised treatment options that can target the cause of the diseases, rather than the symptoms,…

Up to 50% of individuals with Parkinson's disease develop cognitive impairment over time; this study explores the use of 'practice effects' on neuropsychological tests as an early predictor of cognitive decline.

Up to 45% of patients with Parkinson's disease experience impulse control disorders, characterised by a loss of voluntary control over impulses, drives or temptations. This study aimed to investigate whether previously identified genetic and psychiatric risk factors interact towards the development…

The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

Parkinson's disease is the second most common neurodegenerative disease in the world. One of its symptoms is the loss of dopaminergic neurons in the substantia nigra pars compacta.

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

The thesis describes the use of electron paramagnetic resonance (EPR) spectroscopy, in continuous wave and pulse modes, to address the interaction of α-Synuclein (αS) with membranes and the aggregation of αS.

Α-synuclein, a protein associated with Parkinson’s disease, proves to bind with membranes in a surprisingly efficient way. It confirms scientists’ suspicion of the protein’s leading role in the transmission of neurotransmitters between nerve cells in the brain. Publication in PLoS ONE.

Our ability to learn and control movements is essential for engaging in goal-directed behaviour. From buttoning your shirt and driving a car, to cooking dinner and brushing your teeth -- our actions in daily life rely on this ability.

Which brain cell does what, when Parkinson's disease arises? It won't be long before this jigsaw is solved piece by piece. Ahmed Mahfouz, computational biologist, combines bio-knowledge from Leiden with algorithms from Delft and is getting closer to finding the key.

Imagine that you have a chronic skin condition, characterized by red patches of itchy, scaly skin. You regularly notice people staring at your skin and sense their reluctance to shake your hand. Or imagine that you have Parkinson's Disease, causing your hands to tremble and making it difficult for you…

Postdoc Lucia Bossoni has received an NWO Veni grant to research brain diseases for the next three years. She will work in labs at both the LUMC and the Leiden physics institute.

Machine Learning is becoming a more and more substantial technology for industry.

Multiple Sclerosis, Parkinson’s and Alzheimer’s disease are the most common neurodegenerative disorders. Unfortunately, no effective treatments are currently available to halt the progression of these neuroinflammatory diseases [1].

Lysosomal storage disorders (LSDs) are a group of orphan diseases characterized by lysosomal dysfunction or impaired lysosomal catabolism and affect collectively about 1 in 5000 live births.

Living systems scale from unicellular microbes to complex multispecies communities that constantly change over time. Within the theme Development & Disease, we enhance our fundamental understanding of development and homeostasis of living cells and systems. We analyze the normal situation and how stresses…

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

Chemical biologists from Leiden, led by Dr Mario van der Stelt, have discovered substances that can reduce inflammation processes in the brain. This is a first step in the development of potential medicines for the treatment of brain diseases like Alzheimer's and Parkinson's. Published in Proceedings…

Bone research provides plenty of detailed data about the health of a person or a group. This data is not only used to reconstruct the past but also to fight disease today.

Having a chronic somatic condition can result in a variety of impairments in patients’ daily lives, including not only physical complaints such as pain, itch, and fatigue, but also problems of negative mood and impairments in social relationships. Next to disease characteristics, individual difference…

The predication of the effect (efficiency and toxicity) of a drug in a patient is very important in (i) clinical decision support and (ii) the development of novel drug treatments. We apply our technology and methods to find biomarkers for key disease pathways and toxicity in clinical studies and in…

Animal Sciences’ contributions to the Development & Disease research theme include the mechanisms and evolution of embryonic development, the development of cognitive mechanisms, and animal models for understanding mechanisms of human disease.

This thesis describes biochemical investigations of glucocerebrosidase (GBA), the lysosomal β- glucosidase that is deficient in Gaucher disease (GD).

Alzheimer's disease (AD) is the most frequent neurodegenerative disorder and the primary cause of dementia. The neuropathological features of AD include the occurrence of senile plaques, neurofibrillary tangles, decreased synaptic density, and loss of neurons. An obstacle in the study and treatment…

A new research line is the development of liquid biopsy fingerprints to predict early Alzheimer’s disease (AD) stage in human in readily accessible body fluids in human (in collaboration with: Dr. Geert-Jan Groeneveld, CHDR; Prof. Elga de Vries, Free University Medical Center; and others).

Plant Sciences' contribution to the Development & Disease research theme is to unravel the processes that allow plants to adapt to changing abiotic and biotic environmental conditions or stresses, with the aim to contribute to the sustainable production of food, flowers and bio-based products using…

A neural network mimics how our brain works. Evolutionary algorithms use the principle of natural selection to solve complex problems. This kind of 'natural computing' is being used to improve the diagnosis of Parkinson's disease or the production of steel.

Microbial Sciences'contribution to the Development & Disease research theme is to perform world-class research to understand cellular morphogenesis, growth, development and virulence of microbes.
