Depression
and Parkinson’s Disease
Introduction
Parkinson’s disease
is a progressive neurological disorder that primarily affects movement, but its
impact extends well beyond the physical. One of the most significant non-motor
symptoms associated with Parkinson’s is depression. In Australia, as in other
parts of the world, recognising and managing depression in people with
Parkinson’s is crucial for improving quality of life and overall wellbeing.
What Is Parkinson’s Disease?
Parkinson’s disease
is characterised by the gradual loss of nerve cells in a part of the brain
called the substantia nigra. This leads to a reduction in dopamine, a chemical
messenger that plays a key role in controlling movement. Typical symptoms
include tremors, muscle rigidity, slowness of movement, and impaired balance.
However, Parkinson’s also affects mood, cognition, and behaviour.
Depression in Parkinson’s Disease
Depression is common
among people with Parkinson’s, affecting up to half of all patients at some
point during their illness. It is more than just feeling sad or low; depression
can be a persistent condition that interferes with daily functioning, motivation,
and relationships. It may occur before the onset of motor symptoms, during the
course of the disease, or as a reaction to the challenges of living with a
chronic condition.
Why Does Depression Occur in
Parkinson’s?
The relationship
between Parkinson’s and depression is complex. Biological changes in the
brain—such as reduced dopamine and serotonin—play a role, but psychological and
social factors, including coping with physical limitations and the stigma
associated with chronic illness, also contribute. Australians living with
Parkinson’s may face additional barriers, such as distance from specialised
care, limited local resources, and social isolation, particularly in rural and
remote areas.
Symptoms of Depression in
Parkinson’s Disease
·
Persistent
feelings of sadness, emptiness, or hopelessness
·
Loss of
interest in activities once enjoyed, including social gatherings and hobbies
·
Changes
in appetite or weight
·
Sleep
disturbances (insomnia or excessive sleeping)
·
Fatigue
and lack of energy
·
Difficulty
concentrating, remembering, or making decisions
·
Feelings
of worthlessness or excessive guilt
·
Thoughts
of death or suicide
Impact on Quality of Life
Depression can
worsen the physical symptoms of Parkinson’s, making movement and coordination
more difficult. It can also reduce motivation to adhere to treatment plans,
participate in exercise, or engage with support networks. For many Australian
patients, depression leads to a diminished sense of independence and increased
reliance on careers and family.
Diagnosis and Treatment
Diagnosing
depression in Parkinson’s can be challenging, as some symptoms overlap (e.g.,
fatigue, sleep changes, slowed movement). Health professionals use a
combination of clinical interviews, questionnaires, and observation to assess
mood and mental health. Treatment options include:
·
Medication:
Antidepressants may be prescribed, but careful selection is needed to avoid
interactions with Parkinson’s medications.
·
Psychological
therapies: Cognitive behavioural therapy (CBT) and counselling can help
patients develop coping strategies and address negative thought patterns.
·
Social
support: Support groups, community programs, and family involvement are vital,
especially in the Australian context where isolation may be a concern.
·
Lifestyle
changes: Regular physical activity, a balanced diet, and engaging in enjoyable
activities can improve mood and overall health.
