Abstract  Scores of the performance scale of the Wechsler Adult Intelligence Scale (WAIS) declined linearly with age from the 6th decade, whereas those of the verbal scale did not. This decrease in performance intelligence was thought to be related to an age‐related frontal atrophy. The relationship between scores of the WAIS and changes in regional cortical gray matter density were examined in healthy elderly subjects using voxel‐based morphometry. Thirty healthy non‐demented individuals >50… 
oving forward : Age effects on the cerebellum underlie cognitive nd motor declines
TLDR
There is evidence to indicate that there are morphological age differences in the cerebellum that are linked to motor and cognitive behavior, and Cerebellar morphology is often as good as – or better – at predicting performance than the prefrontal cortex.
Fronto‐cerebellar loop and declines in the performance intelligence scale
TLDR
It is found that the right neocerebellum was significantly associated with scores of the performance intelligence scale while frontal lobes were not, and the right cerebral hemisphere, which mediates non-verbal performance, is connected to the right cerebellar hemisphere.
Brain Structural Networks Associated with Intelligence and Visuomotor Ability
TLDR
The results support the parieto-frontal integration theory of intelligence by demonstrating how each core region for intelligence works in concert with other regions and revealed how the cerebellum is associated with intelligence and cognitive functions.

Performance on frontal lobe tests in healthy, older individuals
TLDR
Comparing performance of healthy middle‐aged and older individuals on four frontal lobe tests to provide information regarding age differences in frontal lobe abilities suggested that in a medically and psychiatrically healthy population of older adults, minimal evidence of age Differences in frontal lobes can be documented.
Volumetric asymmetries of the human brain: Intellectual correlates
Neuroanatomical and cognitive correlates of adult age differences in acquisition of a perceptual‐motor skill
TLDR
It is concluded that in a healthy population showing no clinical signs of extrapyramidal disease, age‐related declines in procedural learning are associated with reduced volume of the cerebellar hemispheres and lower nonverbal working memory scores.

TLDR
The results suggest that the size of some cerebral structures may account for a significant, but modest, proportion of the variance in human intelligence.

Is the pattern of intellectual growth and decline across the adult life span different for men and women?
TLDR
Gender comparisons on the WAIS-R suggest that both men and women maintain their crystallized abilities through old age, but show early, rapid declines in fluid ability.

TLDR
A non-verbal problem solving task, viz. a semplified version of Shallice’s London Towers Test, was given to 131 normal subjects to obtain normative data relating to age, education and sex, and the age-related decline of performance in normals was apparent.
