Misfolded proteins are capable of forming tree-like aggregates in Alzheimer's disease
Source: Health News from Medical News Today [2013.11.30]
A method by Rice University researchers to model the way proteins fold - and sometimes misfold - has revealed branching behavior that may have implications for Alzheimer's and other aggregation diseases.Results from the research appear online in the Proceedings of the National Academy of Sciences.In an earlier study of the muscle protein titin, Rice chemist Peter Wolynes and his colleagues analyzed the likelihood of misfolding in proteins, in which domains - discrete sections of a protein with independent folding characteristics - become entangled with like sequences on nearby chains.
Progression towards Alzheimer's disease indicated by an abnormal resting-state functional brain network
Source: Health News from Medical News Today [2013.11.30]
Although we know that mild cognitive impairment is a transitional stage between normal aging and Alzheimer's disease, changes in brain networks during this transformation have yet to be studied. Dr. Jie Xiang and colleagues from Taiyuan University of Technology, China constructed brain networks using resting-state functional MRI data that were extracted from four populations (normal controls, patients with early mild cognitive impairment, patients with late mild cognitive impairment, and patients with Alzheimer's disease) using the Alzheimer's Disease Neuroimaging Initiative data set.

Studies on Alzheimer's disease and other forms of dementia have long focused on what's happening inside the brain. Now an international research team studying Alzheimer's and mild cognitive impairment is reporting potentially significant findings on a vascular abnormality outside the brain.

It's well known that the brains of meditators change, but it's not entirely clear what those changes mean or how the changes might benefit the meditator.
Novel genomic approach reveals gene mutation isn't simple answer in familial Alzheimer's disease
Source: Stem Cell Research News From Medical News Today [2013.11.18]
Researchers at the University of California, San Diego School of Medicine have used genetic engineering of human induced pluripotent stem cells to specifically and precisely parse the roles of a key mutated protein in causing familial Alzheimer's disease (AD), discovering that simple loss-of-function does not contribute to the inherited form of the neurodegenerative disorder.

Long-term response to galantamine in relation to short-term efficacy data: pooled analysis in patients with mild to moderate Alzheimer's disease. [2011.03]
BACKGROUND: This analysis aimed to identify an operational, clinically relevant definition of response achieved in short-term clinical trials to support the identification of patients with Alzheimer's disease (AD) who would benefit most from long-term galantamine therapy... CONCLUSIONS: Patients who demonstrate improvement, stability, or limited cognitive decline 2-5 months after reaching maintenance doses of galantamine are more likely to experience continued benefit from long-term galantamine therapy.
Galantamine improves sustained attention in chronic cocaine users. [2011.02]
Chronic cocaine users are known to have cognitive deficits that are predictive of poor treatment response. Whether these deficits improve with medications targeting specific cognitive functions has not been examined in previous studies.
Galantamine augmentation of long-acting injectable risperidone for cognitive impairments in chronic schizophrenia. [2011.02]
CONCLUSION: Galantamine showed no ameliorative effects on cognitive measures in this 6month, double-blind study of patients with schizophrenia treated with an assured and stable antipsychotic medication delivery system. Galantamine may not be an appropriate augmentation agent for cognitive impairments in patients with schizophrenia at the dose used. Copyright (c) 2010 Elsevier B.V. All rights reserved.
Cessation versus continuation of galantamine treatment after 12 months of therapy in patients with Alzheimer's disease: a randomized, double blind, placebo controlled withdrawal trial. 
Galantamine improved symptoms in Alzheimer's disease (AD) patients after 5 to 6 months of treatment... Treatment was generally safe and well tolerated.
Galantamine improves sustained attention in chronic cocaine users. 
Chronic cocaine users are known to have cognitive deficits that are predictive of
poor treatment response. Whether these deficits improve with medications
targeting specific cognitive functions has not been examined in previous studies.

The Use of Galantamine HBr (Reminyl) in Electroconvulsive Therapy: Impact on Mood and Cognitive Functioning [Active, not recruiting]
The purpose of the study is to see if galantamine HBr (Razadyne) is safe and can help treat
problems with thinking and memory caused by electroconvulsive therapy (ECT).
Effects of Galantamine on Cognition [Recruiting]
Schizophrenia is a chronic disorder with onset of psychosis occurring in late teen early
twenties, with cognitive impairments and negative symptoms frequently emerging much earlier.
Such cognitive impairments and negative symptoms but much milder are also observed in
high-risk groups (such as relatives of schizophrenia patients), who may or may not develop
the full blown psychotic disorder. Our study plans to recruit such non-ill subjects to test
the effects of galantamine on clinical/physiological/cognitive measures. This study serves
several goals: If a drug is found effective in treating subtle deficits, then it will
provide treatment strategy in individuals with schizophrenia spectrum personality disorders
and for early intervention in schizophrenia. In addition, one of the difficulties of
testing a drug on schizophrenia is that patients take other medications (i. e., antipsychotic
drugs) that can change the effects of the test drug. The proposed study will be in subjects
who will not be taking antipsychotic medications. Our study will be carried out in two
sessions, at least one month apart. Subjects will be randomly assigned to the two possible
order of administration: the drug and then placebo, or the placebo and then drug. Subjects
will be given a lead-in 3 days of 4mg/ twice a day of galantamine (or placebo) followed by 8
mg (or placebo) on the 4th day, the day of testing. We will administer a battery of
clinical/cognitive/neurophysiological tests after the 8 mg drug dose.

Oxytocin or Galantamine Versus Placebo for the Treatment of Negative Symptoms and Cognitive Impairments in Schizophrenia [Recruiting]
The project is designed to address the following two primary aims:
1. To determine whether adjunctive oxytocin is superior to placebo for the treatment of
persistent negative symptoms, as measured by the SANS total score, in people with
2. To determine whether adjunctive Galantamine is superior to placebo for the treatment of
cognitive impairments, as measured by improvement on a composite neurocognitive score
in people with schizophrenia.
The investigators will also address the following secondary aims:
1. To determine whether people with schizophrenia treated with adjunctive oxytocin,
compared to placebo, will show greater improvement on markers of negative symptom
liability including: social affiliation, facial affect recognition, olfactory
discrimination, initiation of smooth pursuit and latency of internally-driven saccades.
2. To determine whether people with schizophrenia treated with adjunctive Galantamine,
compared to placebo, will show greater improvement on markers of cognitive impairment
liability including: predictive pursuit, P50 sensory gating and visual-spatial working
The investigators will address the following exploratory aims:
1. To determine whether changes in markers of negative symptom liability are correlated
with changes in SANS total score.
2. To determine whether changes in markers of cognitive impairment liability are
correlated with changes in the composite neurocognitive score.
3. To determine the response to oxytocin of all cognition domains assessed by the MATRICS
battery, and to determine the response to Galantamine of all cognition domains assessed
by the MATRICS, which are not included in the primary neurocognitive outcome score.
4. To determine whether there is a differential response of oxytocin and Galantamine on
the SANS total score, composite neurocognitive score, and with the phenotypic measures
of negative symptom and cognitive impairment liability.
5. To determine whether oxytocin and Galantamine are associated with:
- adverse effects on positive or depressive symptoms;
- adverse effects on motor symptoms;
- adverse effects on laboratory and EKG measures;
- increased occurrence of side effects;
- social interest that is independent of sexual desire.
