One Diffuse Tensor Imaging study suggests that amnestic Mild Cognitive Impairment and Alzheimer’s Disease can be differentiated by Splenium mean diffusivity values.

An interesting study suggests that many of the causes of cognitive decline remain to be elucidated.

A small study showed cognitive benefits of repeated cognitive training in people with Alzheimer’s Disease also treated with Acetylcholinesterase Inhibitors.

The ZARADEMP study (n=4803) provided evidence of a relationship between severe Depression and incident Alzheimer’s Disease (incidence rate ratio: 3.59 [95% confidence interval: 1.30-9.94] which will be helpful in informing management and preventative studies.

The authors of a comparison of 15 antipsychotics suggests that 1st and 2nd generation antipsychotics was not a useful categorisation. This was based on a meta-analysis of studies with 43049 people in total and which was published in the Lancet. The researchers looked at the side-effect profile for the antipsychotics using odds ratios and found that there wasn’t a straightforward relationship between the side-effects and the dichotomous categorisation.

Researchers stratified people with Alzheimer’s Disease according to language and memory difficulties and identified different gene associations.

There is a write-up of a study investigating the use of Memantine for cognitive dysfunction in Bipolar Disorder.

There is an interesting Smithsonian piece looking a series of studies investigating memory including interference, losing teeth and predicting behaviours

An American program called Timeslips has been effective in helping medical students to understand the creative skills of people with Dementia.

There is an interesting paper looking at musicophilia – a craving for music – in Frontotemporal Lobar Degeneration.

An American expert panel is convening to consider diagnostic criteria for Mild Cognitive Impairment in Parkinson’s Disease.

One study looked at the relationship between saturated fat in the diet and CSF AB42 and ApoE which are associated with the pathology of Alzheimer’s Disease.

There is an interesting write-up of a yet to be published fMRI study in which language areas of the brain appeared to be involved in Jazz playing.

There is a write-up of a study here looking at the disorganised firing of place cells in the Hippocampus in a model of Alzheimer’s Disease.

Researchers have developed experimental apparatus to investigate handwriting during brain scans.

One study suggests impressionists use their Insular Cortex and Inferior Frontal Gyrus.

There are new insights into Hubel and Wiesel’s classic work on development in the visual cortex. The new research suggests that Thalamic input not just genetics is necessary for ocular dominance columns.

There is an online brain database at the Montreal Neurological Institute.

An fMRI study used artificial intelligence to analyse the patterns of activity. Emotions were divided into 9 categories and there were found to be distinct differences between positive and negative emotions. The patterns were also distributed throughout the brain rather than in circumscribed areas traditionally associated with emotions.

Researchers found evidence that there is the perception that time passes more slowly with the practice of mindfulness meditation in this study.

A recent study suggests that SIRT1 not only related to aging but also to circadian rhythm. There may be a relationship between these two roles.

Evolutionary PsychiatryNational Geographic features an article about the recently discovered archaic Hominins – the Denisovans which have contributed to the modern human genome.

There is evidence that plants are able to pace the rate of starch consumption overnight suggesting that they have mechanisms for calculations. These calculations are subtle and likely arise from the plant’s biochemistry. This research may be relevant to the phenomenon of Circadian rhythms.

The oldest sample of DNA for sequencing has been obtained from a horse recovered from Canadian permafrost and is over 700,000 years old.

A Mayan city was recently discovered in the Mexican jungle giving insights into the spread of civilisation.

There is a write-up here of research looking at 6000 year old North American cave art which is interpreted in terms of mythology.
