Late-Life Brain Effects of Childhood Adversity - Psychiatry

The likelihood of cerebral infarcts in old age was greater with higher levels of emotional neglect in childhood. 

Whether childhood adversity is associated with stroke in older people is understudied. These investigators addressed the question in a longitudinal neuropathologic study of 1040 nondemented individuals (age, ≥55) who were examined annually (mean follow-up, 3.5 years) and gave permission for autopsy.

Childhood adversity before age 18 was assessed with a self-report scale that covered emotional neglect, parental intimidation or violence, family turmoil, and financial need. Psychiatric evaluations were not conducted. Of the 257 participants who died, the brains of 192 consecutive cases (mean age, 88; 68% female) were autopsied and examined for gross and microscopic cortical and subcortical infarcts in six regions of one hemisphere.

Cerebral infarcts were found in 46% of autopsies. Likelihood of infarcts was significantly correlated with adversity scores (odds ratio, 1.1). In analyses by subscores, the association was limited to emotional neglect. Infarcts were 2.8 times more likely in people who had scored at the 75th percentile of emotional neglect than in those who had scored at the 25th percentile. Clinical stroke, present in 40 participants, was not associated with neuropathology. Findings remained significant after adjustment for numerous socioeconomic and cardiovascular risk factors.

Comment: Despite study limitations (e.g., autopsy of only one hemisphere), the findings are consistent with developmental differences found in institutionalized preschool children, who improved clinically and on neuroimaging after placement in emotionally enriched homes. Shortened telomeres were associated with childhood adversity in the preschool study, and, as a commentator suggests, shortened telomeres might also be a risk factor for stroke. An important clinical question is whether corrective environmental experiences, implemented during younger adulthood, could prevent old-age cerebral infarcts.

Photography and its history

The history of photography is rich with chemical innovations and insights, producing hundreds of different processes to develop images in unique and often beautiful ways. But these historical images can be difficult to conserve, especially since each type of photograph requires a different preservation technique. While two photos could look very similar, they may differ chemically in dramatic ways.

This is where photo conservation scientists like Art Kaplan at the Getty Conservation Institute come into the picture. Art spends his days studying different styles of photographs, their materials and the chemistry that gave life to still life in the early days of photography. His office is loaded with drawers of photographic samples, scientific instruments and a clear passion for frozen history. In our latest video, Art explains the developmental processes of several types of photographs including daguerreotypes, ambrotypes and tintypes.

What a knot

Rules of Writing

Brain Pickings sums up Helen Dunmore's wonderful rules of writing. Helen is a British novelist, poet, and children’s author:

  1. Finish the day’s writing when you still want to continue.
  2. Listen to what you have written. A dud rhythm in a passage of dialogue may show that you don’t yet understand the characters well enough to write in their voices.
  3. Read Keats'letters.
  4. Reread, rewrite, reread, rewrite. If it still doesn’t work, throw it away. It’s a nice feeling, and you don’t want to be cluttered with the corpses of poems and stories which have everything in them except the life they need.
  5. Learn poems by heart.
  6. Join professional organisations which advance the collective rights of authors.
  7. A problem with a piece of writing often clarifies itself if you go for a long walk.
  8. If you fear that taking care of your children and household will damage your writing, think of JG Ballard.
  9. Don’t worry about posterity — as Larkin (no sentimentalist) observed ‘What will survive of us is love’.

Invisible Parents

For thousands of children in the European Union, crossing borders means losing their right to both parents -  because they are the same sex. This film launched on 5 November to change that, and raise awareness of this inequality.
