The Big Picture
Everyone feels sad sometimes, especially after losing someone or experiencing a difficult event. But depression can become much more serious than ordinary sadness.
Depressive disorders affect a person’s mood, thoughts, and physical well-being. These changes can make everyday activities difficult, including eating, sleeping, working, and caring for oneself.
As a Continuing Care Assistant (CCA), you may support clients who have depression. Understanding the signs, offering respectful support, and recognizing possible suicide warning signs are important parts of providing safe care.

Course Notes: Key Ideas You Need to Know
1. Understanding Depressive Disorders
Depressive disorders are a group of conditions that affect a person’s mood, thoughts, and body.
A person may feel sad, empty, or irritable . These feelings occur alongside physical and thought changes that seriously affect the person’s ability to function.
Depressive disorders include:
- Major depressive disorder
- Persistent depressive disorder
- Premenstrual dysphoric disorder
- Substance/medication-induced depressive disorder
- Depressive disorder due to another medical condition
Seasonal affective disorder is another type of depression. Disruptive mood dysregulation disorder is also discussed among other types of depressive disorders.
These conditions have different characteristics, but all involve important changes in mood or emotional functioning.
2. Normal Sadness, Grief, and Reactive Depression
Feeling sad does not automatically mean someone has a depressive disorder.
People commonly experience sadness after difficult events, such as:
- The death of someone they love
- Losing a job
- Another major negative life experience
Grief is a normal, natural response to loss.
The term reactive depression has been used to describe sadness and feelings of loss following a recent experience.
These normal reactions are different from major depressive disorder.
The term reactive depression has also sometimes been applied to major depressive disorder, although physicians no longer use this term.
Key difference: Ordinary sadness following a loss is a normal reaction. Major depressive disorder involves severe, ongoing symptoms that interfere with everyday functioning.
3. Major Depressive Disorder
Major depressive disorder involves severe emotional distress that lasts for weeks and interferes with daily life.
It is also known as clinical depression, although physicians no longer use that term.
A person may experience strong feelings of:
- Worthlessness
- Self-blame
- Sadness
- Disappointment
- Emptiness
These emotional and physical effects can interfere with the person’s ability to complete activities of daily living (ADLs).
How Major Depression Affects Daily Life
Depression can interfere with:
- Sleeping: Normal sleep patterns may change.
- Eating: Appetite and eating habits may be affected.
- Working: Completing work responsibilities may become difficult.
- Studying: Learning and concentrating may be affected.
- Emotional expression: The way a person shows feelings may change.
- Daily care: Completing ADLs may become difficult.
The term affect refers to a person’s feelings, emotions, and moods, including how the person expresses them.
A person experiencing major depression may also think about suicide or attempt suicide.
When Major Depression Can Occur
Major depressive disorder can occur at any age.
It may happen once, following a stressful event such as a death, divorce, or job loss. It may also return repeatedly throughout a person’s life.
Number to remember: Once depression is recognized, medical intervention can make a difference for 80% of affected people, helping them return to regular activities.
This highlights the importance of recognizing depression and receiving appropriate treatment.
4. Treatments for Major Depressive Disorder
Major depressive disorder is generally treated using one or more of three approaches.
Psychotherapy
Psychotherapy involves working with a mental health specialist to explore:
- Thoughts
- Feelings
- Behaviours
The specialist provides guidance and support throughout the therapy.
Drug Therapy
Drug therapy involves medications prescribed by a doctor.
Certain substances can interfere with the beneficial effects of many medications. These include:
- Street drugs
- Misuse of over-the-counter (OTC) medications
- Alcohol
Because these substances can interfere with treatment, their use is generally discouraged.
Electroconvulsive Therapy (ECT)
Electroconvulsive therapy (ECT) is a short-term treatment that affects brain chemicals.
During ECT:
- The client receives anaesthesia to create a dreamlike state.
- The client receives medication to relax the muscles.
- Electrodes are placed on the client’s temples.
- A brief electrical current passes into the brain.
- The electrical current causes a seizure.
The exact way ECT works is not fully understood.
It is believed to change brain chemicals, including serotonin, endorphins, and adrenalin.
These treatments are medical interventions. They should not be confused with the everyday supportive care a CCA provides.
5. Seasonal Affective Disorder (SAD)
Seasonal affective disorder (SAD) is a type of depression that follows a seasonal pattern.
It usually:
- Begins during fall or winter.
- Occurs around the same time each year.
- Ends during spring or early summer.
SAD is common in colder regions, where people spend much of the winter indoors.
Its symptoms may range from mild to severe. Because the symptoms can resemble major depression, SAD is sometimes mistaken for it.
Treatment for SAD
SAD is usually treated with phototherapy, which uses light exposure.
The treatment involves a light box containing white fluorescent tubes.
Key difference: SAD follows a seasonal pattern, and its treatment may differ from treatment for major depressive disorder.
6. Other Depressive Disorders
Several other disorders involve distinctive changes in mood.
Disruptive Mood Dysregulation Disorder (DMDD)
Disruptive mood dysregulation disorder (DMDD) begins in children younger than 10 years.
It involves severe, repeated temper outbursts that are much more serious than ordinary temper tantrums.
The outbursts are greatly out of proportion to the situation in both:
- How long they last
- How severe they are
Persistent Depressive Disorder
Persistent depressive disorder involves a depressed mood for most of the day over a long period.
It is diagnosed when the depressed mood lasts at least 2 years, along with at least four of these symptoms:
- Eating too little or overeating
- Insomnia or sleeping for long periods
- Low energy or fatigue
- Low self-esteem
- Poor concentration
- Feelings of hopelessness
Number to remember: At least 2 years of depressed mood, plus at least four of the listed symptoms.
Premenstrual Dysphoric Disorder
Premenstrual dysphoric disorder involves emotional and mood-related symptoms connected to menstrual periods.
At least five of the following symptoms occur during the week before each menstrual period:
- Mood swings
- Irritability
- Depressed mood
- Anxiety or tension
- Reduced interest in usual activities
- Difficulty concentrating
- Feeling out of control
The symptoms become less noticeable or disappear during the week after each menstrual period.
Number to remember: At least five symptoms before each menstrual period, followed by reduced or absent symptoms afterward.
Substance/Medication-Induced Depressive Disorder
Substance/medication-induced depressive disorder involves an unexplained depressed mood or an extreme loss of interest in most or all activities.
These symptoms occur after:
- Becoming intoxicated
- Withdrawing from intoxication
- Exposure to a medication
The connection between the symptoms and substance or medication exposure is an important characteristic of this disorder.
7. Signs and Symptoms of Depression
Depression can affect emotions, behaviour, thinking, and the body.
Not every sign involves obvious sadness. Some clients may show changes in their daily activities or physical well-being.
Changes in Mood and Thinking
Possible signs include:
- Anxiety
- Feelings of uselessness, hopelessness, or helplessness
- An inability to experience pleasure
- Agitation
- Focusing on the past
- Thoughts about death or suicide
- Paranoia, meaning extreme suspicion about a person or situation
Changes in Behaviour and Daily Functioning
Depression may cause:
- Fatigue and lack of interest
- Increased dependence on others
- Difficulty completing ADLs
- Poor grooming
- Withdrawal from people and previously enjoyed interests
- Reduced sexual interest
- Changes in sleep patterns
- Slow or unreliable memory
These changes may affect how independently the client manages everyday life.
Physical Signs and Symptoms
Depression may also involve:
- Muscle aches
- Abdominal pain
- Headaches
- Nausea and vomiting
- Dry mouth
- Loss of appetite
- Weight loss
Key fact: Depression can appear through emotional, behavioural, thinking, and physical changes.
8. Supporting Clients With Depression
A CCA can provide important day-to-day support to a client experiencing depression.
The goal is to provide respectful care while supporting the client’s comfort, safety, and everyday activities.
Build a Positive, Supportive Relationship
Show the client that you enjoy spending time with them.
You can do this by:
- Listening carefully
- Showing interest in the client’s life
- Maintaining a positive approach
Some clients who have never received a depression diagnosis may not recognize that they are depressed.
Others may not describe themselves as depressed because they do not understand the symptoms.
Do Not Minimize the Client’s Feelings
Avoid statements such as:
- “Cheer up.”
- “Snap out of it.”
These comments can suggest that the client is exaggerating their feelings or can simply choose to stop feeling depressed.
Instead, listen and show genuine interest.
A positive experience may encourage additional positive experiences.
Encourage Rest and Nutrition
Rest: Encourage the client to rest. Rest may help restore energy and provide refreshment.
Nutrition: Encourage proper nutrition. Maintaining normal blood sugar and energy levels is important.
Encourage Activity Without Exhausting the Client
Encourage clients to participate in activities and social interactions.
These experiences can improve the client’s outlook and sense of well-being.
Important: Do not tire the client by encouraging too many activities.
Balance encouragement with the client’s need for rest.
Support Activities of Daily Living
Encourage clients to complete their normal ADLs when possible.
Provide assistance when needed, including with:
- Bathing
- Preparing meals
- Taking in enough fluids
Helping with these everyday activities can support the body’s normal balance and prevent other health problems.
Provide a Safe and Stable Environment
Clients with depression may feel they have less control over their surroundings.
A safe, secure, and stable environment can help them feel comforted.
Safety is especially important when a client expresses thoughts or intentions of suicide.
Follow the Care Plan
Follow the care plan when supporting a client with depression.
For example, a care plan may state that a client:
- Cannot have access to medication bottles.
- May take medication only from a dosette or blister-packaged container.
These restrictions depend on the individual client’s care plan.
The CCA must respect the directions provided rather than changing medication access independently.
Recognize and Report Suicide Warning Signs
Remain alert for signs that a client may be considering suicide.
Report any warning signals of suicidal intent to your supervisor at once.
When a client expresses intentions of suicide, sharp items, belts, cords, or similar objects may need to be locked away to maintain safety.
Suicide warning signs deserve special attention because some suicidal actions are impulsive rather than planned over time.
Nova Scotia CCA Note
Sorrentino’s Canadian Textbook for the Support Worker, 5th Edition emphasizes following the care plan and reporting suicide warning signs. In Nova Scotia, the CCA Occupational Standards of Practice further explains the CCA’s role. A CCA watches for changes in a client’s condition, including emotional and thinking changes, while providing care. This is called a point-of-care observational assessment. It is not a nursing assessment and does not allow a CCA to make a comprehensive clinical evaluation.
Nova Scotia also sets specific conditions for medication assistance. A CCA may help a client open a prescribed daily routine medication when the client cannot do so independently. For medication that is not a prescribed daily routine medication, specific practice conditions must be met or the task must be properly delegated by a regulated health care professional. Medication assistance must follow the care plan, the directions supplied by the regulated health care professional, and applicable employer requirements.
Why this matters in Nova Scotia: A CCA can observe and report changes, provide care-plan support, and assist with medication only within permitted limits. The CCA does not independently diagnose depression or decide on medication treatment.

9. Warning Signs of Suicidal Intent
Suicidal feelings and actions can be symptoms of an illness that is treatable.
Some suicide attempts are planned carefully over time. Others happen impulsively, without much thought beforehand.
Recognizing warning signs is an important safety concern.
Warning Signs Involving Words or Feelings
Watch for:
- Signs and symptoms of depression
- Repeated statements of hopelessness, helplessness, or desperation
- Expressing an interest in killing oneself
- Describing a suicide plan, including a specific method, place, or time
- Telling someone about final wishes
Warning Signs Involving Behaviour
Other warning signs include:
- Losing interest in friends, hobbies, or previously enjoyed activities
- Giving away prized belongings
- Putting personal affairs in order
- A sudden change in personality or mood
- A major change in personal appearance
- Not recovering from a loss or crisis
- Suddenly taking serious risks
- Refusing food, fluids, or medication
A change in mood may include becoming unusually happy after a period of depression.
A change in appearance may include a normally well-groomed person becoming untidy or unwashed.
Safety: Do not overlook warning signs simply because the person seems happier or has not spoken directly about suicide.
Immediate Help When Someone Is Suicidal
When a person is feeling suicidal, the following actions are important:
- Call a doctor, emergency room, or 9-1-1 right away for immediate help.
- Make sure the person is not left alone.
- Prevent access to large amounts of medication, weapons, or other objects that could be used for self-harm.
Self-harm means intentionally hurting oneself to cope with feelings such as anxiety, depression, numbness, self-anger, or loss of control, or to regain emotional control.
For the CCA, the specific reporting direction is clear: Report any warning signs of suicidal intent to your supervisor at once.
Nova Scotia CCA Note
Sorrentino explains the importance of immediate help when someone is suicidal. Nova Scotia also provides crisis services that students should know about.
The 9-8-8 Suicide Crisis Helpline offers free support by phone or text, 24 hours a day, seven days a week. Nova Scotia also has a Provincial Mental Health and Addictions Crisis Line at 1-888-429-8167, available at any time.
For immediate danger, Nova Scotia advises calling 9-1-1 or going to an emergency department. These crisis services do not replace a CCA’s responsibility to report suicide warning signs to the supervisor at once and follow workplace emergency procedures.
Why this matters in Nova Scotia: Knowing the available crisis services helps students distinguish between obtaining crisis support and responding to immediate danger. Reporting and workplace emergency responsibilities still apply.

10. Depression in Older Adults
Depression is common among older people.
Older adults may experience several losses and changes that contribute to depression.
Losses That May Contribute to Depression
These include:
- The death of family members or friends
- Medical conditions that affect health
- Loss of physical functions
- Loss of independence
Other factors that may trigger depression include:
- Loneliness
- Losing a beloved pet, friend, or partner
- Poor nutrition
- Taking too much, too little, or incorrectly using prescribed medications
- Unwanted effects of certain medications
- Losing control over personal finances
- Memory impairment
- Recently moving from independent living into long-term care
Why Depression May Be Missed in Older Adults
Depression in older adults is often overlooked or incorrectly diagnosed.
Some older clients do not admit to feeling depressed.
Instead, they may complain about physical discomfort, such as aches and pains.
Others may become:
- Agitated
- Irritable
Depression may also be mistaken for dementia or delirium.
When this happens, the depression may remain untreated.
Key fact: Depression in older adults does not always appear as obvious sadness.
11. Ways to Reduce Depression Risk in Older Adults
Several supportive measures can reduce the likelihood of depression in older clients.
Support Physical Well-Being
Helpful measures include:
- Providing adequate, nourishing food and water
- Ensuring regular bowel movements
- Supporting regular medical checkups with a family physician or nurse practitioner
- Ensuring medications are taken correctly
- Avoiding excessive use of OTC medications or alcohol
Support Social Connections and Enjoyment
Other helpful measures include:
- Offering support and encouraging contact with others
- Providing opportunities for physical activity
- Encouraging time outdoors in fresh air and sunlight
- Providing opportunities to interact with pets
- Offering activities that stimulate the senses
- Encouraging participation in reminiscence groups
- Creating opportunities for clients to feel wanted and needed
These measures address physical, emotional, and social needs.
When assisting with care, the CCA should follow the client’s care plan and the directions relevant to their role.
Exam Clue Words
Certain words can change the meaning of an important fact or care direction.
- At once: Any warning signs of suicidal intent must be reported to the supervisor immediately, rather than waiting.
- Follow the care plan: Medication access restrictions must follow the client’s specific care plan.
- At least: Persistent depressive disorder involves at least 2 years of depressed mood plus at least four listed symptoms. Premenstrual dysphoric disorder involves at least five listed symptoms.
- May: Sharp objects, belts, cords, and similar items may need to be locked away when a client expresses suicidal intentions. This wording does not mean every client with depression has identical restrictions.
Common Mix-Ups
| Wrong Idea | Better Idea |
|---|---|
| Feeling sad after a loss always means major depression. | Grief and sadness can be normal responses to loss. Major depressive disorder involves severe symptoms lasting weeks that interfere with daily functioning. |
| Seasonal affective disorder has no particular timing. | SAD follows a seasonal pattern, usually beginning in fall or winter and ending in spring or early summer. |
| Depression in older adults always looks like sadness. | Older clients may report aches and pains or appear agitated and irritable. Their depression may also be mistaken for dementia or delirium. |
| A sudden happy mood means suicide risk has disappeared. | Unusually happy behaviour after depression can be a warning sign of suicidal intent. |
| Encouraging activity means keeping the client constantly busy. | Activities and social contact may help, but the client should not become overtired. |
