Parkinson’s disease (PD) is a long-term neurodegenerative disorder of the central nervous system whose symptoms generally come on slowly over time, mainly affecting the motor system. The most common genetic … Continue Reading Scientists identify a role for main Parkinson’s gene in the brain.
The human brain is the source of a person’s thoughts, emotions, perceptions, actions, and memories. One challenge for neuroscience is to achieve an integrated understanding of brain-wide interactions, particularly the … Continue Reading Study identifies new function for the hippocampus.
Marijuana is a psychoactive sedative drug and is derived from the hemp plant, Cannabis sativa. Its leaves and buds can be smoked, taken in food, brewed in tea or taken … Continue Reading Neuroimaging shows that marijuana users have low blood flow to the brain.
It is known that rigidity and loss of muscle function associated with Parkinson’s is linked to a depletion of dopamine in the part of the brain that controls movement. However, … Continue Reading Gene mutation identified for early onset of Parkinson’s disease in Caucasians.
Study shows that structure of toxic tau aggregates determines type of dementia, and rate of progression.
Recent efforts to develop a treatment for Alzheimer’s disease and other dementias have focused heavily on removing toxic tau proteins from the brain. The tau protein is known to bind … Continue Reading Study shows that structure of toxic tau aggregates determines type of dementia, and rate of progression.
Alzheimer’s disease is a neurodegenerative disorder characterized by progressive memory loss and cognitive dysfunction. It affects more than 30 million people worldwide, including an estimated 5.4 million Americans. One in … Continue Reading Dysfunction in neuronal transport mechanism linked to Alzheimer’s disease.
The onset of ALS, also known as Lou Gehrig’s disease, is marked by the gradual degradation and eventual death of neuronal axons, the slender projections on nerve cells which transmit … Continue Reading Researchers identify the key instigator of neuron damage in sporadic and inherited ALS.
Alzheimer’s disease (AD) is characterized by cognitive decline, alteration of synaptic transmission, and neuronal death brought on by accumulation of neurofibrillary tangles in neurons and amyloid beta in the brain. … Continue Reading Study shows that vesicles appear to also contribute to Alzheimer’s disease.
Alzheimer’s disease is characterized by the degeneration of neurons in the hippocampus and cortex, and the appearance of neuritic plaques and neurofibrillary tangles. Although the precise cause of Alzheimer’s disease remains … Continue Reading Researchers elevate brain protein to allay symptoms of Alzheimer’s in animal model.
For decades, scientists have known that people with two copies of a gene called apolipoprotein E4, or ApoE4, are much more likely to have Alzheimer’s disease at age 65 than … Continue Reading Study shows why people with the ApoE4 gene are more susceptible to Alzheimer’s disease.
The CDC estimates that more than 1.3 million Americans visit an emergency department each year because of a TBI-related injury. The late effects of TBI are of great interest, however, … Continue Reading Largest ever study identifies link between TBI and Parkinson’s, but not Alzheimer’s.
In the United States over 1.7 million cases of traumatic brain injury (TBI) are reported yearly, with the predictive correlation of cellular injury to impact tissue strain lacking, particularly for … Continue Reading First ever imaging of brain cells’ reactions to concussive trauma in real-time.
Parkinson’s disease (PD) is a degenerative neurological disease characterized by tremor, slowness, and gait and balance difficulties that affects approximately 1 million people in the United States. The symptoms are … Continue Reading Study identifies key to Parkinson’s disease neurodegeneration.
Obesity is a global health problem that poses a major risk factor for life-threatening diseases such as cardiovascular disease, cancer, and neurodegeneration. Recent studies have identified specific loci associated with … Continue Reading Study maps a molecular link between insulin-sensitivity and obesity.
Alzheimer’s disease is a devastating and progressive neurodegenerative disease affecting approximately 5.3 million people in the United States, including almost half of the population at 85 years and older. Microscopic hallmarks … Continue Reading New blood test detects early Alzheimer’s in large-scale study with unprecedented sensitivity.
Neurodegeneration in Alzheimer’s disease is thought to be caused by the abnormal behavior of amyloid-beta molecules, which are known to gather into tough fibril-like structures called amyloid plaques within patients’ … Continue Reading Human amyloid-beta shown to act as a powerful antibiotic in the brains of animal models.
