In people without autism, their brains prune (trim, remove) synapses that we no longer need as we grow. Synapses are connections between nerves and cells that send messages to each other. So when we learn or sense anything, a synapse forms.
However, there’s a lack of this pruning in those with autism. So everything you learn, see, feel, observe, and take in, your brain becomes overloaded with that and it doesn’t always get rid of what they don’t need. It’s like a bush that doesn’t get trimmed in our brain, taking over (imagine the roots as the nerves, the branch as a synapse and the leaves as the cells). The unnecessary synapses take over and make life really hard, as their senses are continuously overwhelmed.
