Investigations






CT Brain


He was reviewed by physiotherapist and occupational therapist in ward every day.


Physiotherapist reported:

  • Power of both upper limbs was 3/5 while lower limb power was 2/5. Muscle tone was normal. Wasting of both upper and lower limb musculature. Needed moderate assistance from supine to lying on his side but maximal assistance from lying on his side to sitting and from sitting to standing.

  • Balance while sitting was reported to be fair.

  • Knee control when bridging fair

  • However he was deemed unsuitable for walking frame ambulation due to poor knee control and was suggested to use reclining wheelchair.

  • Unable to do TUG/ JAMAR

Occupational therapist reported that

  • Patient was alert and co-operative, good orientation. MBI 23/100.

  • Sensation was absent up to both elbows and both calves.

  • Power both upper limbs was 3/5 and lower limbs was 1/5. Muscle tone was reported to be normal.

  • Hand function assessment: Able to extend elbow joints and able to grasp and release stacking cones with left hand. Right hand grasp was documented to be weak. He was able to hold on to cup and wash his face with minimal assistance.

Progress in ward

  • He was treated with antibiotics and was started on intravenous fluids. Bowel movement was regulated in ward. Caregivers were taught on various methods to minimize fall risk and also to use weighted spoon and plastic cups with handles in order to enable him to be as independent as possible. •

  • Premeal capillary glucose in ward ranged between 6.1 to 14.4.

  • No documented postural drop in blood pressure.

  • He was co managed by our neurology team who offered lumbar puncture which he and his son refused.

  • He described burning sensation over hands and feet to be bothersome and interrupted his sleep.

  • Patient was found to be having low mood in ward. We gathered that at home, patient had often mentioned that he will not recover and he is being a burden for his family.

He was started on esitalopram to help with his mood and pregabalin for the pain. In ward, he claimed pain had much improved and was able to sleep longer once pregabalin was started

During discharge, he was scheduled for an outpatient visual acuity assessment and DEXA Bone scan along with occupational therapy and physiotherapy appointment. A geriatric clinic appointment date was scheduled 6 weeks after discharge to reassess mood and MOCA. Patient and his son were not keen for outpatient MRI Brain appointment.


Medications on discharge:

  • T. Folate 5mg OD

  • T. Cardiprin 100mg OD

  • T. Atorvastatin 20mg ON

  • T. Calcium Carbonate 500mg BD

  • Syp Multivitamin 10ml OD

  • T.Esitalopram 5mg OD

  • T. Pregabalin 75mg OD

  • T. Metformin 500mg BD

  • T. Bisoprolol 2.5mg OD

GDS and MOCA was performed just before discharge to be used for comparison during clinic visit.


Unable to perform trail making test


DIAGNOSIS

1. Neuropathic pain due to bilateral peripheral axonal motor & sensory neuropathy likely due to diabetes & alcohol abuse.

2. Recurrent fall due to multiple factors; bilateral lower limb sensory motor neuropathy, deconditioning.

3. Possible pseudodementia likely due to geriatric depression  Mixed dementia (Alzheimer & vascular)

4. Folate deficiency


  • However within a month of discharge, he was readmitted for worsening pain over all limbs and meal refusal since discharge. He had become bedbound since discharge and was completely dependent on his wife for his BADL.

  • He had missed all his appointments and stopped taking most of the medications except gabapentin (which they were buying from a private hospital).

  • He had lost a significant amount of weight since the last encounter, he was previously using size M clothing but the clothes were visibly too large for him. Unable to weigh him in ward due to lack of chair/ bed weighing scale. He was lucid and 4AT: 1(unable to count backwards).

  • Swallowing test in ward, patient was able to swallow.

  • Often refused meals because he had no appetite. When fed, patient only ate 2-3 spoonfuls and refused the remaining portion.

  • He was reviewed by the hospital dietician who prescribed ONS in addition to high protein soft meal. Patient’s family was also advised to bring his favorite food items and serve snacks such as yogurt and ice cream between meals to increase his calorie intake. However patient refused all of it and hardly finished his ONS servings, often refusing after consuming one third to half of the serving claiming he felt full.

  • According to his son, he had often expressed feeling hopelessness and had said that there is no point in living as he was becoming a burden to others. He was assessed by psychiatry team in ward and was diagnosed with adjustment disorder.

  • In ward patient at times refused to participate in physiotherapy sessions as he felt there was no point.

  • He was started on T.Mirtazapine 15mg ON to help with his mood and appetite and at the same time T.Gabapentin 100mg BD was started to help with the neuropathic pain.

  • He was evaluated by a speech therapist in ward who found swallowing to be normal. Patient preferred soft or liquid based meals compared to solid food. His wife was taught to prepare meals of his preferred consistency.

  • The hospital dental team had examined him and found the dentures to be in good condition and well kept. There was no oral lesions that may be causing pain during eating.

  • Meal refusal was a major cause of concern for his wife who used to cry whenever he refused meals. Possibility of NG tube feeding to supplement his poor oral intake was raised several times throughout the admission and the importance of nutritional support for recovery was explained however patient firmly refused NG tube. His son and wife were in the loop regarding patient’s decision and decided to respect his wishes.

  • After family conference, patient was allowed to return home once he no longer needed nasal prong oxygen support in the hope that his mood and appetite would improve in a familiar environment. Respite care options was discussed with the son & wife in order to reduce caregiver stress.

  • We arranged for a home visit the following week and a geriatric clinic appointment in 4 weeks to reassess his mood and appetite. Unfortunately patient passed away at home a few days after discharge from ward.

POINTS TO PONDER

  • Could his low mood and chronic pain be alleviated by any other modality apart from pharmacological methods?

  • If MNA score was available and indicated malnutrition, how would you proceed?

  • Assuming hand grip strength score in this patient and was found to be weak, what would be the treatment approach?

  • Should we consider NG tube feeding In elderly patients with anorexia after all other measures have been exhausted?

  • Should patients wishes in this regard be taken into consideration although his decision was potentially harmful?
