Procrastination is not Laziness. It is typically associated with ADHD.

Talking about the labeling of every single human behavior, Procrastination is making the charts.

Nobody’s lazy anymore: the new vocabulary for ‘Laziness’ is ‘Procrastination’.

The most disturbing part is that Procrastination is being deemed as an emotional disorder and major feature of ADHD.
I can be easily distracted, though not lazy.
Procrastination is Distraction to me.

Distraction does slow-down productivity, although it’s not associated with Lethargy.
In fact, we are mostly hyperactive when distracted.

ADHD rarely manifests individually, it is a component of most Mental Disorders, last but not least, Autism.

Neurons are divided into Recipients and Receivers separated by Synapses, spaces where neurotransmitters temporarily pool up, before being absorbed by receiving Receptors.
This process is continuous and interchangeable.

In ADHD, the neurotransmitters are not re-absorbed in the recipient cells, accounting for deficiency of serotonin and dopamine, major players in Attention and Reward, resulting in impaired cognitive function.

ADHD treatment is gaining momentum in the cure of Autism and Clinical Resistant Depression.

Latest findings from Dopamine Transporter scans, show abnormalities in Young-Adult Autistics.
We know that Dopamine has an important role in motor-skills Memory.
Parkinson’s disease is the most common form of neurodegenerative illness characterized by loss of motor coordination.
Lack of dopamine is a general symptom.
The specific pathology of Parkinson’s is the inability to recycle unused dopamine clogged in Transporters.
The same pattern applies to autism. What was previously thought of autistic Stimming, could be early- onset Parkinson’s, with autistics having 6 times more chances of developing the disease later in life.
New dopaminergic medications are under study.
