For many decades, Alzheimer's disease research has primarily focused on impairments within cortical and hippocampal regions, which are thought to be related to cognitive dysfunctions such as memory and language deficits. The exact cause of Alzheimer's disease is still under debate, making it challenging to establish an effective therapy or early diagnosis. It is widely accepted that the accumulation of amyloid-beta peptide in the brain parenchyma leads to synaptic dysfunction, a critical step in Alzheimer's disease development.

The role of the cerebellum in the neurodevelopmental outcomes of preterm infants has often been neglected. However, accumulating evidence indicates that normal cerebellar development is disrupted by prematurity-associated complications causing cerebellar injury and by prematurity itself. This hampers not only the normal development of motor skills and gait, but also cognitive, language, and behavioral development, collectively referred to as "developmental cognitive affective syndrome.

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder characterized by the selective and progressive loss of motor neurons, leading to gradual paralysis and death within 2 to 5 years after diagnosis. The exact underlying pathogenic mechanism(s) remain elusive. This is particularly the case for sporadic ALS (sALS), representing 90 % of cases, as modelling a sporadic disease is extremely difficult.
