    00:01 When it comes to treating depression in the elderly, you wanna take a multimodal approach starting with therapy.

    00:08 Be supportive and possibly also psychodynamic. Explore with that patient on a one-to-one basis.

    00:15 Their fears, their hopes, and let them open up about what they're experiencing.

    00:20 Now we wanna avoid polypharmacy in this population but you might consider treating with an antidepressant especially if the more non-invasive approach of therapy isn't quite helping enough. Antidepressant you might consider include SSRIs, MAOIs.

    00:36 Here are some examples of SSRIs. You may also try tricyclic antidepressants or something like mirtazapine which is an atypical antidepressant but has a very nice side effect of actually enhancing sleep and also appetite which are often two things that the elderly people will struggle with during depressed times.

    00:58 You might even consider a stimulant medication like methylphenidate.

    01:02 This can often help to perk up the very depressed elderly patient and then other things you might consider are electroconvulsive therapy.

    01:10 So we've talked about this in other lectures and in particular, you wanna consider electroconvulsive therapy or ECT in a geriatric person when they are really struggling such as not eating, not getting out of bed, becoming catatonic, maybe having some psychotic features or in the elderly person with intractable suicidal thoughts. Now, I did mention tricyclic antidepressants before.

    01:38 They're an option but you wanna be very, very careful with them especially in the elderly because they do act at the muscarinic receptor causing stimulation and this can lead to sedation and more importantly can even lead to cardiac abnormalities which can cause big trouble for that patient. When it comes to bereavement, the elderly are as I said earlier more likely to experience losses of loved ones or friends and it's really, really important to distinguish normal grief reaction from depression.

    02:14 So let's go through some of the criteria. So in normal grief, you'll see people have illusions maybe seeing the deceased every now and then, but they know that they're not really there.

    02:25 They may attempt to resume their daily activities and work even if they're struggling through it.

    02:31 They might feel a little bit guilty and sad for outliving their friend.

    02:35 Some symptoms can resolve within about a year and there maybe some sleep disturbance.

    02:41 All of these is pretty normal in the grieving process.

    02:44 Now it becomes abnormal when symptoms persist for more than a year and the worse of the symptoms are persisting beyond 2 months.

    02:54 Very severe symptoms that are actually impairing day to day function.

    02:57 When the individual feels absolutely worthless, that's a very worrisome sign and there's significant sleep disturbance and weight loss, that's also very distressing and a sign for abnormal grief. Any hallucinations or delusions, so meaning that the patient is no longer reality testing and they're actually experiencing some psychotic symptoms.

    03:22 That's abnormal grief and when the person is not even attempting to get back to their day to day life, that's also a very troubling sign and likewise any suicidal thoughts is a huge warning sign that this person is not just having normal grief but they may have enter a major depressive episode. Now, abnormal grief needs to be treated and usually that's done with a combination of psychotherapy and also psychopharmacology.

    03:50 Another thing to be attuned to in the elderly is their sleep.

    03:55 So the incidence of sleep disorders actually increases with aging.

    04:00 Elderly people will often report difficulty sleeping, daytime drowsiness and often daytime napping.

    04:06 Some of the causes for these are, them actually experiencing a general medical problem, environmental problems, too many medications and it could be just normal changes associated with aging. Side effects of sedative hypnotic drugs in the elderly are also really important to note and this is another reason why it's important to avoid too many medications. It can cause memory impairment, ataxia, paradoxical excitement or rebound insomnia. None of which are good. When it comes to treatment, benzodiazepines are another thing to look out for. So before ever adding a benzodiazepine to a sleep regimen or a treatment regimen at all, you want to be very careful in the elderly population.

    04:54 These medications can only exacerbate problems cause addictions, disrupt sleep and increase the eldery's risk for falls.

    05:04 Another important note to consider is elder abuse which unfortunately does happen and something you need to know about for your exam. So about 10% of people over 65 are potentially abused and this may be actually underreported number because the perpetrators usually a caregiver or a trusted family member or friend and usually doesn't go reported. So different types of abuse could be physical, sexual, psychological, verbal, neglect, exploitation or misuse of finances.

    05:40 I wanna talk about a little bit more about treatment in the elderly and we're gonna explore each of these ideas a little bit further.

    05:47 Restraint, medications, nursing homes and old age homes.

    05:52 So when it comes to restraints, these are sometimes used in an agitated elderly patient and it's very unfortunate because it's quite dangerous. So restraints tend to be overused especially in nursing home settings and hospitals. When somebody is restrained, they're gonna suffer both physically and psychologically. It's a very scary experience.

    06:14 So you wanna try to avoid restraints in the elderly and instead try alternatives like closer monitoring maybe one-to-one with the nurse or doing something like a tilted chair.

    06:24 When it comes to medication, again avoid multiple medications.

    06:29 Patient will only suffer side effects and drug-to-drug interactions.

    06:34 Let's consider this case study now. Joan is an 85-year-old woman.

    06:41 She comes to her PCP with the complaint of feeling tired and wants to know if there's a medication that could help perk her up. You perform a thorough history and a physical exam and you get some collateral information from her daughter.

    06:54 So Joan takes over 25 different medications you learned for her multiple medical issues.

    07:01 There are no general medical problems that you can think of that are making her so tired during the day and so you're thinking about doing something with her medication, but rather than adding a new medicine what might be more helpful? Of course, see if you could eliminate 1 or 2 medications from her list.

    07:22 She's on polypharmacy already so maybe by taking a few off might go a long way and helping to perk her up.

    07:29 In terms of nursing home treatment, these are places that provide care and rehab for the chronically ill and impaired patients as well as for short and long term care for people who just can't return to their prior living arrangements. About half of patients will stay on permanently once they go to a nursing home even if it's originally only intended for rehab needs.

    07:51 So these are institutions where people can actually live out the rest of their lives.

    07:57 Important to note and something that is occasionally thought of in care when the home living situation isn't appropriate for the patient.

    08:07 So we've touched upon a few topics here having to do with the elderly.

    08:13 So keep in mind that this is a topic that can come up in your exam and the key thing when you see an elderly patient is to make sure they're not on polypharmacy and also make sure that you're assessing them for the psychiatric disorders that anyone in the general population could absolutely be facing.
