Brain Disorder

What is a brain disorder?

A brain disorder refers to any condition or disease that affects the brain’s structure, function or chemistry, leading to a range of physical, emotional and cognitive symptoms. Here are some common types of brain disorders:

Category Description
Neurodegenerative disorders These involve the progressive degeneration of nerve cells and include conditions like Alzheimer’s disease, Parkinson’s disease and Huntington’s disease.
Mental health disorders These affect mood, thinking and behaviour, including conditions like depression, anxiety, bipolar disorder and schizophrenia.
Traumatic brain injuries (TBI) These result from external force impacts, such as concussions or more severe head injuries.
Stroke This occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients.
Epilepsy A neurological disorder characterised by recurrent, unprovoked seizures due to abnormal electrical activity in the brain.
Brain tumours These are masses or growths of abnormal cells in the brain, which can be benign (non-cancerous) or malignant (cancerous).
Infections Conditions like meningitis or encephalitis, which are inflammations of the protective membranes covering the brain and spinal cord, usually caused by infections.
Congenital brain disorders These are conditions present from birth, such as cerebral palsy or hydrocephalus.
Autoimmune disorders Conditions where the immune system mistakenly attacks the brain, such as multiple sclerosis.
Metabolic disorders Conditions that affect the brain’s ability to process certain chemicals and nutrients, like phenylketonuria (PKU).

Is addiction classed as a brain disorder?

In this section, we take a deeper look into addiction as a brain disorder and understand why many experts widely accept this notion. We also will take a look into the argument that addiction isn’t a brain disorder and is a result of other factors.

Addiction is a brain disorder

Addiction alters brain function and structure
Many experts widely recognise addiction as a brain disorder because it causes significant changes in both the function and structure of the brain. 
Changes in the brain’s reward system
Research shows that addiction disrupts the brain’s reward system, which is responsible for feelings of pleasure and satisfaction. This disruption leads to a cycle where the brain increasingly craves the substance to achieve the same pleasurable effects, reinforcing the addictive behaviour.
Impact on motivation
Addiction can significantly affect the brain areas responsible for motivation. This often leads to a situation where individuals prioritise substance use over other important activities and responsibilities, such as work, relationships and personal health, because the substance becomes the primary source of motivation.
Memory disruption
The brain changes caused by addiction can disrupt memory functions. This disruption makes it difficult for individuals to remember the negative consequences of their substance use, which can perpetuate the cycle of addiction as the brain’s ability to learn from past mistakes is impaired.
Impaired impulse control
Addiction affects the brain regions responsible for impulse control, such as the prefrontal cortex. This impairment makes it harder for individuals to resist the urge to use substances, even when they are aware of the potential harm. This loss of control is a key characteristic of addiction as a brain disorder.

Addiction beyond a brain disorder

Behavioural perspective
Some believe addiction should be viewed more as a learned behaviour influenced by environment and experiences rather than a brain disorder. They argue that focusing solely on brain changes can lead to neglecting the importance of personal choice and social context in addiction.
Moral and ethical concerns
There are those who argue that labelling addiction as a brain disorder removes personal responsibility, potentially leading to stigma against those struggling with addiction as being ‘ill’ rather than individuals making harmful choices.
Cultural and societal influences
Critics also point out that addiction rates and perceptions vary significantly across different cultures and societies, suggesting that broader societal factors play a crucial role and should not be overshadowed by the brain disorder model.

While the brain disorder classification of addiction has strong scientific backing, it’s important to recognise the complexity of addiction and the diverse viewpoints on how best to understand and address it.

The benefits of recognising addiction as a brain disorder

By viewing addiction as a brain disorder, it opens the door to a huge amount of positives for the people experiencing addiction, as well as the field of addiction studies and psychology. Here are a few ways that viewing addiction as a brain disorder can yield benefits:

 

  • Reduces stigma: Seeing addiction as a medical condition rather than a moral failing helps reduce the stigma around it, encouraging more people to seek help without fear of judgement.

 

  • Promotes compassion: Understanding addiction as a brain disorder fosters empathy and compassion. It shows that people struggling with addiction aren’t just making bad choices but are dealing with a complex health issue.

 

  • Supports recovery: Framing addiction this way can motivate individuals in recovery. It reinforces that they can manage their condition and lead fulfilling lives with the right treatment and support.

 

  • Influences policy: Recognising addiction as a brain disorder can impact public policy, leading to better funding for research, prevention and treatment programmes and promoting health-based approaches over punitive measures.

Do rehab centres view addiction as a brain disorder?

Yes, they do. An addiction rehab centre’s programme treats addiction as a brain disorder by integrating medical and therapeutic approaches. It views addiction as a chronic illness, focusing on changing brain chemistry and behaviour through medications and therapy.

Here’s what you could expect during an addiction rehab programme:

Detox

Detoxification, or detox, is the crucial first step in treating addiction. It involves cleansing your body of the addictive substance and managing withdrawal symptoms. During this phase, you might face physical and emotional challenges like anxiety, sweating, nausea and tremors. Medical professionals are there to provide medications and support to ease these symptoms, ensuring a safe and comfortable detox process.

Therapy

Therapy is essential for uncovering the root causes of your addiction and developing coping strategies. Traditional therapies, such as Cognitive Behavioural Therapy (CBT) and individual counselling, help you understand and change your thought patterns and behaviours linked to addiction. Holistic therapies, including yoga and art therapy, aim to improve your mental health and promote relaxation. These therapies work together to heal both your mind and body, fostering a sense of well-being and resilience.

Aftercare

Aftercare provides ongoing support as you reintegrate into society. It includes continued therapy sessions and support groups to help you maintain sobriety and prevent relapse. Aftercare programmes offer resources and strategies to strengthen your relapse prevention plans, ensuring your long-term recovery success.
